Gamefaqs - For all your Game Faq needs
Shoryuken - Great Forums site
Dynamic Drive - Perfect for adding that certain something to your site.
Gamespot - Even though for complete access you have to pay, you still get plenty gaming information for free.
Ign - Same as Gamespot, but I find that you get more flexibility to move around the site.
Abstract-Anime - Great site for Anime backgrounds.
Animewallpapers - Another great site for Anime backgrounds.
