Well after playing P3 for 15 Hours, I've decided not to get P4. I Just don't enjoy the combat system at all. They made it so it feels like if you don't have the enemies weakness, why bother attacking. And since I can only customize the main characters attacks it just makes the other characters there to get attacked. Plus I don't like the concept of "If the main Character dies, game over since obviously the other characters can't revive him." The music in the game irritates me, and I don't feel like I've gotten any stronger since day 1 of the game.
I can see why some folks would like it, but it just isn't for me =(.
