Alright, then. Every Nippon Ichi game is good, and yeah FF Tactics is also good. Tactics Ogre is fun, but one if my favorite games is Jeanne D'Arc. Its pretty underrated. Its one of the few SRPGs that I've totally completed.
But those are Japanese titles. For western ones, obviously Heroes of Might and Magic is an excellent series, as is King's Bounty. Disciples 3 is good, too, nut critics didn't really like it very much.
