The PSN trophies are hilariously outdated, mostly because they were created for the PS3 release of the game, and completely forgotten. I mean, the "Warrior of Light" trophy is rewarded to someone that completed "the Main Scenario", but it actually only counts the 2.0 original Main Scenario.

Also, this game has quite an extensive list of achievements. Right, they are ingame, and can't be seen on Steam, but they are still there.
