Above are maps of India and Arabia at my end date, showing religion map mode and country map mode.

Report of 'Spread of Islam', start date: 1st February 600. End date: 1st January 720. Playing as: Observer
Timeline:
1st February 600: (and possibly a while before), the state religion of Malwa is 'Sunni'.
16th July 626: Malwa is eaten by Chauhan
12th October 627: Sunni Islam appears simultaneously in Mecca and Medina, Quraysh forms the Rashidun, which holds Mecca.
5th October 628: Rashidun eats Banu Nadir (Medina)
16th January 629: Rashidun eats Yemen, the whole country converts to Sunni and becomes cores of Rashidun
28th June 639: Rashidun gains Najd from the Sassanids
20th June 644: Rashidun loses Mahra, Najd, Medina and Asir to the Sassanids
1st July 686: Rashidun loses Najran to the Sassanids

Additional detail:
India:
Islam spread slowly but surely throughout India during the seventh century, but Malwa was the only state in India to ever adopt Islam as its state religion, even though places like Gujarat had both of their province's religions as Sunni for more than 80 years. As the eighth century started however, Hinduism was starting to push back hard against Islam. Given around 200 years more, Islam would have disappeared from India.
Arabia:
Here Islam was much more push and pull throughout the whole period, it took some land in Ethiopia but was quickly pushed out by Aswan, it twice gained control of the Lakhmids but both times it was not adopted as the state religion and both times it was pushed back. Until the eighth century it was mostly moving forwards, taking more land, but then Orthodoxy and Zoroastrianism started pushing against it and both were making a lot of progress. Only one Byzantine province ever adopted Islam: Al Karak. Given another 120 years, Islam would have been gone from Arabia. The Rashidun never really stood a chance, they took the states they could but on their Northern border they faced Byzantium and everywhere else they faced the Sassanids, who had started blobbing long before Islam even appeared and only started to fall apart around 715, when they lost Basra and some land around the Black sea to Byzantium, and Sind gained independence. It could never have been enough however.

Had I started a little later, at a point closer to the founding of Islam, the Rashidun might have won. They could have strengthened their position in central Arabia then pushed against the Sassanids as equals. As it was however, the Sassanids got there before Rashidun and had already cleared away all the weak states. The Sassanids need to be weakened in order to stop them from building a huge Empire as they did in my game, and it should be easier for states to convert to Islam.

What do you mean by 'subject-specific requirements'?

Thanks for the report. This looks like a rather plausible alternative history scenario of the Sassanids beating back the Islamic conquests, but I'm afraid this kind of development is too common.

I removed the 'subject-specific requirements' -line. It was only confusing.

Here is my report of the "Fall of Rome" scenario.
I started as a observer the 1:st of Januari 380 and ended the 2:nd januari 481.
This is what it looked like in 481.

But how did this happen?
Well, I will describe it all from the start.
Right from the start Rome had some trouble with nationalist and patriots rebels.
In 384 Rome started the conquest of Gynedd, wich they ended up just taking money from.
Due to a Regency Rome hit 0 legitimacy in May 403.
A non-Rome related thing was that 402 Huns got into a personal union under Alans.
In July 407 Brittany broke free from Rome, and they got Oxfordshire, Essex and Cornwall.
After this Rome went slowly upp to max legitimacy.
But between 433 and 447 they had a chain of horrible events that lead to -3 stability, and 25 legitimacy. I'v never seen such unlucky situation before.
The 1:st of April, 448 Rome splits into Western Roman Empire, and Byzantium.
In June 441 Gallia breaks free, with most of the french region.
In September 443 Algiers breaks free with 7 coast-provinces in Africa, and the Moors gets some provinces due to patriot rebels.
In 445 Allemani starts "the Allemanian Conquest of Zyrich" war aigins Western Roman Empire, wich ends 3 years later in tem taking Zyrich and Bern.
In Februari 464 Armangnac breaks free, with Bearn and Gascoge.
After this comes another long session of peace in the Western Roman Empire, and nothing more happens if you exclude the fact that Gallia and Brittany gets some more provinces due to patriot rebels.

As you might have noticed, I didn't focus on Byzantium. They basicly got loads of rebels all the time, and fell apart slowly.
Rome did split, but one thing bothered me the whole time, and that was that noone attacked Rome. Even when they was weak as hell, the only one who attcked them was Allemani. They basicly just fell because of rebels, not wars.
Other then that, I think the whole "Fall of Rome" scenario worked out quite well.

It's good to see that the Fall of Rome works at least somehow. It seems like there's enough internal issues for Rome, but the Barbarian invasions still need to be worked on.

Yeah, I agree. As fast as Rome gets -2 or -3 stability, they just gets destroyed by rebels. Btw, I love this mod, and I will try to do the "Spread of Christianity" if or when I get time for it. All to help you develop this awesome mod.

Here is my report for the 'fall of Rome'. I was interested to see if Rome would fall with a start date of 51 AD, so that's the start date for this playtest.
End date is 503 AD. Played as observer. Conquest of Paradise enabled.

Results:
- Rome did survive, and even managed to annex the moors, all of modern great Britain, a couple of barbarian provinces, Armenia, Bosphorus, and is pushing into the Arabian peninsula by vassalizing Nabatea.
- Throughout the playtest Rome showed very little signs of instability/rebellion, the only notable lost provinces being Crete and Lesbos (probably due to both being islands) to Morean patriots.
- Rome didn't split
- Also, no nation dared to attack Rome directly during the test. Rome did manage to get involved in wars by alliances, but won those wars easily.
- Rome's stability was at 3 almost non-stop (I think this has to do with them having no techs to spend their monarch points on early game, thus stocking the points)

Other interesting notes:
>on Orthodoxism:
- Orthodoxism began to spread fairly early. Rome converted around 200 AD. Around 300 AD there were almost no other religions left in the empire. Around 500 AD nearly every nation in Europe, North Africa, Arabia and the Middle east was orthodox
>on Asia:
- The Han dynasty managed to grew quite large but eventually got overthrown by Zhou and Sung.
- A strange phenomenon happened where some nations in India and China (especially newly formed nations, but 'old' nations like Han and the Japanese factions as well) started at or reverted to a relatively very low tech level. I have no idea what could have caused this, but it could very well be my own copy of EU4 messing up ;).
>on America:
- The natives have no problem keeping up with the Europeans in technology. In fact, almost every nation in the world had the same tech level at the end of the test.
- Due to the native mechanics in Conquest of Paradise, some native Americans were able to colonize huge parts of North America with their sole colonist over time, most notably the Iroquois (occupying most of Canada in 500 AD)

I also did a quick test manually lowering Rome's stability in a seperate savefile, and while no one still attacked them, the rebels still did their job and formed Gaul and Palmyrene.
Thus the problem - I think - is the permanent high stability Rome seems to have, and the lack of serious outside threats.

Although from Auxilior's report it seems the fall of Rome can work out somewhat, Rome is very unlikely to fall with an early start date. Although it's the wrong threat, I would like to end with a few quick thoughts/suggestions on Rome (hope you don't mind too much ;) ):
- more minor event driven instability/rebellions (historically this would be for example Roman generals proclaiming themselves emperor);
- more events related to major crises (third century crisis, barbarian invasions, the Huns (the poor Huns always die pretty quickly));
- a Roman faction system much like the Chinese Ming/Han dynasty (maybe a strange idea, but this could make playing Rome much more interesting)

And about other issues:
-Native Americans - at least in this playtest - seem too powerful with conquest of paradise enabled. This could of course easily be solved by disabling the expansion.
-Historically, orthodoxism should spread much slower before ~200-250AD, and spread slower outside of Roman borders.
-To make it more interesting to play a single game from 50 - 3000 AD (or any timespan longer than, say 500 years), it would be best if all huge empires other than rome and china naturally rise and fall (although this is probably very hard to realize)

First of all: I started the game with 0.51 patch. in year 200 i changed it to 0.6
Played as: observe.

year 50 to 300:(no west rome, huns got destroyed fast)

Greece, macedonia, syria, gallia and algiers formed out of roman empire. sarmatians and quadi got very big and on east
side it was parthia and han. the orthodox religion spreads very quickly.

year 300 to 459 (no byzantium, parthia did not disapear, east africa rome appeared in ethiopia, francia got destroyed fast)

wales took whole breat britain+ireland. denmark and quadi expand fast. algier took over moors. greece and macedonia got
attacked by rome many times. Han got very huge and orthodox spread even more. parthia lost some provinces to greece and had
alot of fights against rome. but they still managed to expand in west india.

year 459 to 716 (islam spread fast, rashidun came from syrian and beduin culture)

burgundy expansion expands. hand is huge and parthia has to fight with orthodox and sunni religion. rome won a few fights
against greece and all smaller europe states.

year 716 to 1198 (around 1050 catholics came up in nothern europe, islam was nearly destroyed in 716 to 1000 by romans and
parthia, parthia got parted around 1050 in 1, half side islam and east side beluchistan zoroastrian)

rome and greece nearly destroyed rashidun. sarmatians attacked islamic nations and formed the islamic vasall nation sarmatian persia. sarmatian and persia are orthodox. kazakh got formed from kushan as zoroastrian nation. saxony and quadi got eaten up by gallia and roman empire. greece had alot fights with gallia against roman empire. russia and goths
destroyd burgundy. sind got formed as hindu nation but will lose against buddhist hindustan (paradox^^).

notes:
alot of nations werent destroyed in these 1100 years. gallia, quari, samartia etc.
parthia was alive until 1050. then it took 50 years to part this big nation. in year 1140 parthia was still there, whout any religion.
east africa rome went and came as a protectorat of rome with the name 003 or something like that.

Is there any way that you know of to make the game do an autosave at a specific date? I'd hate to have to sit and babysit an entire game hoping that I stumble upon it around the right time, or at least within the time that I would still have autosaves available.

Not that I know, but that's the reason why I have only required the end date to be after a specific date. You can let it run all the way to 9999 if you want.

I was running this mod in observer mode for some time (Started in 51 AD) and when I got to the time when the sunni religion appears, as Rome was still extremely large and controlled the area where Islam originated, they became Sunni and their country changed to Rashidun. This seems kinda strange to me and it would probably make sense to put a restriction on who this can happen to, so that the Roman Empire doesn't spontaneously disappear and become Sunni.

There were a few other things I noticed before this point. First the Roman Empire had no real threats of collapse. I was actually quite impressed by the amount of provinces that the Vandals and Hannover (Formed by the Angles I think) were able to steal from the Empire, but in about 600 years the Romans had hardly any rebels. Greece gained independence relatively early on with some provinces scattered about and Gallia gained independence as a single province "Empire", but other than that the Romans faced no interna challenges. It appeared as if they remained at +3 stability for most of this period and it would be nice to see more instability for the Empire.

I also felt like the Orthodox religion overwhelmed the religions in Northern Europe (particularly Germanic) too quickly. I know that eventually this should happen, but it didn't feel right for every Germanic tribe to be Orthodox.

The last thing I noticed was that Han had some of the same issues as Rome. It quickly gobbled up all of China, Korea, Southeast Asia and Northern India by around 600 AD with no challenges internally or externally.

I also started a game as the Angles in 51 AD and have played just under 100 years. I did notice some more stability problems in the Empire which was good, although they didn't seem to get many rebels from that. It also seems as if there is a real lack of action between the germanic tribes. other than the wars I have started there have not been a single war between them and only one involving Rome (which Rome started). It would be nice if there could be a lot more warfare to make them feel more barbarian like. I'm not sure if it was just some coincidental thing in my game or a general trend but more war would definitely be great.

Overall though the mod seems pretty great and it blows my mind how you managed to put it together. I feel like it will consume much of my time (and already has). Great work!

Any fix on multiplayer soon?
