Fifa2008.net could have tm issues, but if they release a game, and you hold it until then, it could be a good mini-site name, selling the game through amazon or something. None of the names here will attract the big bucks, but I reckon you could turn a small profit on all of them. (I hate erotikpage.com though, you'd have to pay me to take that, don't know why, its the intentional incorrect spellings I think!)
Any way, best of luck.
