I like to have everything unlocked. I'm playing Megaman X Command Mission right now and that means filling up the Sky Room. For games like Final Fantasy it when I beat the Omega Weapon of the game, no matter what game when I beat the strongest optinal boss I fell great. I also have to get my favorite team to Max Level (30, 50, 99, 255) with all there techs or what have you. Don't really care about max stats, just getting to the Max Level is sometimes a chore in itself. Also if I don't use them I don't really bother leveling them up either.
