Here is a list of Game Top Sites that are pretty good. I have used all of them before. www.MMOwns.Com/top100 - Its a new one, would use now to aquire a higher rank http://www.worldofwarcraft100.com/ - Pretty Large topsite, Page Rank 5. Recommended for large sites. http://www.warcraft-gaming.com/wow-topsites/ - Relativly new, but the main site has many visitors. http://www.topgamesites.net/ - Large Topsite, Supports a Plethora of games. Takes a large amount of votes to get to a noteable rank. More to be added after dinner.
Just thought I would comment and say that the (topgamesites.net) one is not so good as if you look at the way it links to your site it does not actualy use a propper hyperlink back to you, it uses a PHP script which is useless I think. ooh that is funny to see my topsite there also, I own that www.Warcraft-Gaming.com so I gotta say that one is the best
