It's either MMOs or MMORPGs. MMORPGS, MMORTS, MMOFPS, MMOTG, MMOMG, etc are subsets of MMOs. Therefore, it should be the #1 source for MMOs. For header let it read, Massively Multiplayer Online Hub. MMO might confuse people--unlikely, but possible. Include an About page for new MMO gamers and DO NOT refer to them as "noobs." Make the game list another page w/ its link as a tab by "Home". (Same for "Other Pages") Make it seem less Japanese only oriented by illustrating other MMO types, ie WoW, tycoon MMOs. DELETE redundant "Categories" box--the pic boxes serve this purpose well.

My number 1 rule for websites: ALPHABATIZE & ORGANIZE.  (List games in ALPHA order.)

Thanks for the tips, working on it. Plan to delete the catagory section, make a tab at the top for the game list, and other pages, and also for a forum.

 As for the redundant MMO and MMORPGs bit, believe it or not search engines like Google actually reward sites for that kind of key word loading... this is why a lot of sites have long titles, for example look at Game Spot's:

 GameSpot:Video Games PC PlayStation 2 Xbox 360 Wii PS3 GameCube PSP DS GBA PS2 PlayStation 3

 How annoying is that title? Especially when you bookmark a site like that and have to delete the excess words.

 Until searche engines are improved all I can say is don't hate the player, hate the game ~__~

 
Feel free to drop some more suggestions folks, I've added a bunch more reviews!
 

Looks nice.
