The only three free ones (two fo them very popular) that I know of:
Runescape (only played for briefly, 3 hours at the most, and seems very simplistic)
Anarchy online (only played briefly, but it is 3d, and better graphics than Runescape, want to get into this one more often)
Hero (just heard of this one, graphics that rival any pay MMO. want to play this one more)
