I happen to disagree with the OP on just about everything with S04. But alot of people feel the same way as you I guess. I really liked S04, it wasn't anything revolutionary but for some reason everygame nowadays has to or it sucks.
The story was good for me, the characters were alright....except for Sarah OMG! Now that ones voice actor, made me want to blow my brains out. Gameplay was fun, but I wish it would have been a little bit more like S0TeoT. That is my 2nd fav game of all time by the way. :P
But I own both IU and S04 and I can say that while I did enjoy IU, S04 is the MUCH better game. Both games have their flaws, but decent games.
Try The Last Remnant if you can. Good game, has some lag issues but just install it and you'll get over it like I did. ^^
Also you can probably find IU on amazon or ebay for 20 bucks now. Definitely worth the purchase.
