Why hasnt anyone sed WoW yet? Its the greatest game EVER! (Not to sound like a game-geek.)

runescape is all i can think of

I like Air Rivals, good 3D arcade fighter combat and graphics.

Lord of the Rings Online is actually good enough to shake the throne of WoW and its got a longer trial time :D

I would say World of Warcraft..but you said you wanted a game you didnt have to pay for.  If your looking for a free MMORPG I would say either Warrhammer or Guild Wars I havent played either one but I know that WOW is better lol thats my opinion but anyways if you want PVP (player vs player) then go warrhammer if you want more PVE (player vs environment) go guild wars if you want a good freakin game with awsome PVP and PVE and 11,000,000 players and more and more and more..go WOW(got carried away lol). and one more thing I heard the requirements for warrhammer is crazy so idk and AOC (Age of Conan) cost per month to let you know...so you pick and tell me if this helped you any but I would go WOW its your choice though so have fun..

Air Rivals is a great MMORPG =). Its basically Space Cowboy but owned by different company.
Also you should try Lunia,an arcade kind of fighting game, which is also now owned by another company (Ijji).
Speaking of ijji, GunZ the Duel is definately worth to try out, Soldier front is a decent MMOFPS, while Gunbound is like a Worms kind of game.

alright try out
