How to have more than 8 sims?

[Porkchop Sandwiches]

I just got this crazy idea to build a giant house and put every single sim in sunset valley to live in it, but I need more than 8 sims to make this possible. If you have any guides please post'em. Youtube videos can help also. I have a lot of mods but no expansions.

I dunno about every Sim in the game world in one house.... but you can bypass the 8 sim limit with a few mods.

Primarily you need this one:

Including the integration option. This will basicaly uncap your household limit.

It'll break the portrait panel if you have more than 8 sims though, to fix that you'll need this:

This will let you cycle through more sims than normally could be displayed in the panel.

And if a non-active household has more than eight members, the EA StoryProgression is going to break, so you'll have to replace it with this:
http://nraas.wikispaces.com/StoryProgression
The maximum number of sims that NRAAS Story Progression will track in a non-active lot is set under the Maximum Size: Human option under Lot Options. It's set at 8 by default and you can change it to whatever you want. There's also Maximum Size: Pet which defaults to 6.

Automous Woohooing is also broken if you have more than 8 sims, to fix that you need to toggle some options in this mod

And finally, if you travel to another game world when your household is more than 8 sims..... bad things can happen. Data could be lost, relationships could be blanked, perhaps even losing sims in transit. To fix that, you require this:

With all those mods you should be able to have larger households. But it'll be very laggy and chaotic if you still go too big.

As an aside, you're going to have more glitches if you do this, so this mod is absolutely essential.

That will catch most problems and prevent them from destroying your game allowing you to keep on playing without interruption.
And this one can help things run better with less lag and waste

That will clean up some nonsense and inefficiencies that tend to slow down your game and inflate it with clutter.

You can corrupt your save file in that way so backup first

Yes, and save often. When you do save, use Save As and make a new file each time rather than saving over your old file. (I like to alternate through two or three filenames so I don't end up with a million one saves.)

thanks so much guys! love the help.

You can try the Saver mod from NRAAS. It can help remind you to save every once and a while, for an interval you can customize. And it cycles you through a number of save files, that you can also customize.
