Check the sticky in the flash game section. The staff is not going to change anything to this current site, so you will have to wait for AGv3 to launch, which might have a better section system or an easier way to find games of a certain kind.
Why did you post it in this section then?? Answer still stands, though. They will probably add such a section if needed, but until then, there should be plenty of opportunity using a bettered search system to find the multiplayer games.
If I'm not mistaken... there has been a discussion about this question i the AGv3.0 forum between users and Cormyn before. The matter was taken into consideration by the staff, allthough cormyn warned upfront that this is probably not likely going to happen, since every game has it's designated category and with the tags it would be easy to find a multiplayer game on the future website, so the matter was unresolved and the thread locked.
