Missables, Achievements, NG+, chapter select.

[RAWRmonger]

I have googled these but I'd like some clarification.

1) NG+ doesn't carry over stuff like the car upgrades, but what about chapter select?
2) Does chapter select allow me to repeat any chapter? Like the part where the game becomes linear?
3) Google tells me the only missable is an achievement by fighting a certain boss on Easy. Is that true? Can you spoil me the boss?

I wanted to do a perfect save in my first playthrough and wanted to go on Easy to speed things up, I'll also try and break the game ASAP.

--"perfect save"--

Well, depends what you mean by this. If you're interested in a full bestiary, that's impossible in a single-playthrough, because there is one side quest that has 3 possible picks (different besitary entry for two of them) and you can only choose/do one of them in a playthrough.

If you mean achievements, I think you can get them all in one shot but yeah you'd need to get a good guide because some are easy to miss. (edit - also you have to do all the post-game now, not just main-story)

Chapter Select works exactly the same as NG+, it just allows you to pick where you start from. In other words, every time you Chapt. Select, you lose quest progress and other stuff, just like NG+. But yes you could use it to repeat sections if you want - it just won't work for a "perfect save". (edit) You can keep a main save and just do chapt. select whenever you want to replay parts, just don't overwrite your main save so you can go back to it (nothing will carry back to that older main save, ofc).

There's one very minor sidequest with Ignis that is missed if you go past ... uh ... Chapt. 3 or 4 maybe? It's the one where he asks you to go look at a certain place. If you go too far Chapt. wise the place is inaccsible and can no longer be done, thus the sidequest becomes void.

My definition of "perfect save" is kind of soft, in truth.

The most important thing to me is having everything done right (lore wise), and the most content accessible, by which I mean the world, usually when I get an airship. I personally call them "open saves", but I'd have to explain it every time.

I also like using achievements to keep track of what I have to do.

For example:
- In FF9 I made sure to view all the ATEs, but I didn't care to collect every piece of equipment or find every item (as long as I got that Treasure Hunter achievement). My "best" save stays at the point where you have the airship but before the events that put the world restricted later on.
- In FF12, I wanted the characters to follow their lore jobs but I am likely ignoring the in-game trophies (which were present in the original game, not Steam's achievements) and like 9, I don't need to get a sample of every equipment.

I am not OCD to the point of wanting to have 99 of every item, however.

I'm not an expert with Achievements (don't care about them much), outside of that I Platinum'd on console on release, because back then you got Plat. just by playing the game, nothing tricky.

The boss Achievement you mentioned is Ifrit, sorry forgot to mention that.

DLC's have to be completed on Normal for an achievement, although you may be able to use Easy for most of it and then switch to Normal close to the end, not sure.

Since you can "return to the past" (once you reach Chapt 9) and finish up any of the main open-world section stuff whenever you wish, the only things that matter is explore/complete everything in chapt 10-13 before leaving each one since you can't return to those in a single playthru.

Btw, Easy changes almost nothing in the game. I think enemies may do slightly less damage to Noct/party, but this doesn't equal much of a time-difference - if Noct dies on Easy (not easy to do since the bro's will try to Rescue you) Carbuncle appears to revive and put on a short super buff, but that's about it. Carbuncle will not appear in certain fights/areas. The game's default difficulty is generally so easy to begin with there's no point in "breaking" the game, if I understand what you mean by that. If anything, most try to make the game harder using a lot of self-restriction.

There really isn't much you can perm. miss, as your Google searches already confirmed. :)
