The two games online that i have gotten into recently is RF Online and Nine Dragons, more so RF Online
RF Online - RF Online is a sci-fi mmorpg with graphics more like everquest 2 than world of warcraft it is free unless you wanna buy extra's, the main server isclosing at the end of october because of copyright stuff, however there is a private server me and DragonCross use call RF Equilibrium the link is ( The private server concept art is a bit disturbing, the game is free of this though, One of the races dresses a bit skimpy though =/)
