I don't really think the layout needs more colour, as punkie90 said, but it needs a bit more balance. On the right sidebar, you use images for your category headers (ie: affiliates, topsites, etc), but on the left sidebar, it looks a bit empty because it only uses text headers. ^^; Just something I noticed, not necessarily wrong or anything. @_@; But I especially like how organized the content is and everything. Especially the game pages. ^^; And a few of your links aren't working (Fossil TCG, PKMN2000).
Nice site. ^^; May I ask what font you used for the top banner? *likes it* >>
