Crysis is only on PC. COD4 is on both xbox360, ps3, and PC.
Not sure how is 360 much cheaper than the ps3. Of course, if you don't care about blu-ray, then it is a wasted perk that is offered on PS3. You can get the arcade version of the 360 for $250, but it does not have any harddrive in it. If you get the premium $299version, it has a smaller hd at 20Gb compare to 40Gb for the ps3. Wireless is standard on PS3, but you have to buy an additional attachment for wireless for the 360. I'm not sure how much it cost for that attachment. Of course, just like the bluray, if you dont care for wireless and will jsut use hard wire ethernet cable, that is another wasted perk offered on PS3. Finally, you have to pay for Xbox Live indefinitely, which cost $50 a year, every year as long as you want xbox live, or until MS say it's free. Or you can go shop around and get xbox live for $38 a year. This is the cost you have to add on top of the price you pay for your console. So, as I was saying, i'm not sure if I agree with you that xbox is cheaper.
