I played EP once, and gave up about 3/4 into the game. The story was entertaining, but I couldn't take the uber complex gameplay :
In order to summon a decent persona, you must get in battle with a certain monster, negotiate with certain character(s) and correctly answer the random questions. Now repeat for about 30 tiemes until you have enough tarot cards and you're good to go. Oh, and your Persona will be obsolete as more powerful ones are obtainable 2 dungeons later.
SRSLY!, I'm really glad they over simplified Persona 3 in this aspect.
The insane encounter ratio and bland looking dungeons without on-screen map (dur hur, take 10 steps, pause, check map, take 10 steps, pause, check map, take ....) only made it worse.
