If you're into sports/competetive games then i would recommend renting/buying Rockstar Games Presents: Table Tennis. That game is
alot of fun to play with a bunch of friends. The graphics arent astonishing but it does look like a next gen game. Gameplay isnt that hard to learn but takes a while to master, although when you play against other people it might just turn into "who can hit the ball harder" contest, lol. but its still alot of fun.
Another sporty game that i liked was fight night round 3, these graphics are amazing, every time you look at the boxers faces you can swear that its almost the real thing. When you're fighing in an old warehouse, you can
even notice the dust in the air. This game is really easy to get into because you controll the right analog stick to punch, so it never turns into a button mashing contest if you play with friends.
Also, i heard (but havent played) that new Dead Rising game is pretty sick. You play in a mall infested with thousands upon thousands (literally) of zombies, and you have a million different ways to save people or escape. Each playthrouh gives you exactly 7 hours playtime to do whatever you wish to get out alive, and theres always a different ending that coincides with whatever you did. Also, i heard you can use like a million different weapons to kill the zombies. iunno, it seems entertaining if ur into that sort of thing.
EDIT: Yeah Yarr beat me to the whole deadrising promo lol.
Xbox 360 is a good system if you dont set your hopes rediculously high like everyone else has. If i were you i would buy one now before the holliday season starts, because thats when alll the goooood shit comes out.
