Tactics Ogre: Reborn

• The WORLD system unlocks after you beat the game, which allows you to return to previous points in the story and make different choices. This means that missables are few and far between, as most things can be redone with a better result at the expense of time. However, if you want to make sure you have access to the most stuff as you progress, make sure you're checking the Warren Report Talk section and reading new entries when they come up. Some topics unlock new sidequests and areas.
