I have the dead rising demo for xbox. Its pretty good. But Dead Island sounds a bit better.
Dead Island is Fallout with zombies. I dont know how it gets much better, having loved fallout 3 and new vegas. A good buddy of mine says its great.
Left 4 Dead games are too short in my opinion. It took me 45 mins to beat the first game on normal. Mw3 on normal took 5 hours and that is too short also.
(Cod2 was perfect in length

)
Now, Operation Flashpoint Dragon Rising is taking me awhile.

I like challenging games and games that i cant beat in one sitting. L4D1 was like a warmup for something better.
