I think the Call of Duty 4 is the best one. I also like the boxing game of<URL SNIPPED> nintendo Wii. Because I drip sweat and get away from the big pressure in the life. It was such a great experience when you get refresh in the game. So many thanks to PS2 and Wii bringing me so much fun. And I also fortunately find many cheap quality PS2 flash cart, Wii controller, boxing gloves, wheel, NDS flash cart from sourcinggate.com. It's great!
COD4 is a good game, however I think that Battlefield 2 is better. The whole question is moot however as what type of game are you referring to? There is no overall best game. maybe best game in a genre, but no best game overall
