Star Ocean: The Last Hope

Each character has 100 different Battle Trophies. So in order to get this to pop you have to get 270 of them amongst the 9 characters. Another thing is that the game makes 2 saves one for your actual game data and another for the collection data.
This allows you to have your completed trophies on other play throughs. Although you can't finish the ones that are not complete (example: you need 3000 kills,if you get 2999 in first play through you won't get the trophy on a different play through by getting one kill.

**SPOILER ALERT**
Achievement hunters beware that Faize leaves the party on the second disc when you go back to Aeos.
