I had a quick scan down that list and as an avid gamer I was shocked that there were 3 games I had never heard of, and I don't want to sound big headed but if I haven't heard about them, they're hardly going to be considered the best games around since I know most games that come out.
Halo, COD and Half Life all failed to feature so that list is pretty useless and I realise some of you most likely hate Halo or COD or whatever, but they all changed gaming, mostly for the better so in that sense they are probably the best games out. When you have sports games on a list as a best game but nothing really popular and main stream except Bioshock, than you're off. Also, Bioshock is not the best game. Sorry to all you fans but it just isn't. Was a great play, don't get me wrong but it shouldn't have gotten the top spot, not sure what should have but it shouldn't. Heck, in my opinion of 'good games' only 2 of the games on that list should have made it.
Just my opinion.
