i know at least 75% of the mmo games on the internet but i still don't know them all try putting all the mmo games here that u know and the site to download them from if it's of any use if u think this sucks just say it i really don't mind.........
I don't even know what some of those are, but I'm pretty sure neither Counter-Strike, America's Army, or Ricochet are considered MMOs. To be an MMO, I'm pretty sure you have to have hundreds of people on the same map/server at a time, and those have a limit(which is generally non-existant on an MMO, to an extent.)
