Okay, something's wrong here. My favorite Xbox 360-exclusive game, as of right now, is Tales of Vesperia. Now granted, I haven't had the chance to play that many 360 games yet, but that where I stand as of right now. Here's where things are wrong.
I like P4 more than TOV.
None can stand before the might that is the PS2! (except for the SNES) (And also, I have a feeling the 360 library hasn't peaked yet.)
Anyways, more ways in which P4 is better than P3: your characters do not get tired out in the dungeons. Theoretically, you could crawl dungeons forever provided you have enough items and you them and your healing spells judiciously. This is good. One less thing to worry about.
Another thing you don't have to worry about; girls don't get jealous of other girls. This actually makes some of the social links easier than they were in P3. You can date as many girls as possible, and none of them seem to care that you're seeing them all at once. And, much like in P3, your character is a chick magnet. Virtually any girl close to your age and nice enough to talk to you can fall for you. Of course, I can't determine if their feelings are merely platonic crushes, or romantic crushes, or romantic crushes that eventually shift to platonic crushes. Oh whatever. Let's just say that girls are totally hot for you in P4. Realistic? Not very much. But then again, it must have something to do with being the chosen one. Your character in P3 was the same way . . .
So what are you waiting for? Play P4 already! It has everything you could want!
P.S. When Yukiko is wearing her black short-sleeved blouse and white miniskirt on days off from school, she looks so cute! She's a doll.
P.P.S. But she can't replace Yukari-chan. No female RPG character can.
P.P.P.S. Except Arche Klaine.
P.P.P.P.S. And Rinoa Heartilly, if you count games that I have a love/hate relationship with.
