I recently picked up Final Fantasy XIII for the 360 and I wanted to know if there are any achievements I should know about a head of time so I don't screw up and have to play through again.
The two you want to watch out for are the following:
- Loremaster (Discerned the full attributes of 100 enemies.): just make sure you use Libra multiple times on enemies until all attributes are filled out (no question marks). There are way more than 100 enemies in the game, but some enemies only appear in one chapter, which is really annoying if you're trying to be a completionist.
- Treasure Hunter (Held every weapon and accessory): make sure you
equip every item before you sell it, anddon't sell weapons, even if you think they're junk. You don't want to sell weapons because you'll need to upgrade at each weapon at least once (upgrading creates a new item) to get the achievement.
The rest of the achievements you'll get as you progress through the game, or can be completed once you complete the game. Some of the achievements can only realistically be done after you complete the game.
