For those who have a Xbox360, Oblivion is a must have.
First things first, in my opinion this is not a conventional, RPG, personally i hate rpg's they're boring most of times, but oblivion mixes action, adventure and a little bit of RPG, which makes him a non-boring game, some people say "i don't know if i buy it, because it's looks boring". Looks boring, but it's not. this is the best elder scrolls to date.... now those are booooring.
The graphics, there's nothing much to say, in xbox 360 they look just awesome, some bugs though, but like i said, it's near perfection.
One thing that i want in a game is a good soundtrack and sound effects, in this point, oblivion didn't fail too. History: Oblivion's history it's just great, with hundreds of quests during the game... if you don't want to do just the main-quest, do little quests, join guilds and brotherhoods, buy houses and horses, steal houses, do whatever you want (steal have a price in oblivion if you get caught :) ), oblivion offers hours and hours of fun.
Conclusion: yeah my review is a little messed up, but i made my point, oblivion is great, awesome, if you don't have live and/or love single player and you want hours of fun and entertainment, get your A$$ of that chair and go buy it now!
Peace :)
