if youve got quite a load of ram and freespace, you might wanna try LineageII =] i had heaps of fun with that.
The official servers are pay2play though, but theres quite a lot of populated private servers (free!)

Just for the record, its sortof like WoW, except the graphics dont look as cartoony, and theres no Alliance Vs Horde.
Anyway, not sure if youll like it or not..

if not, you might liek Guildwars like unknown was saying?
