Loved Age of Decadence. Will probably buy this once it's "fully" released

Hi all roleplayers!

I liked to play some MMORPGs (at least for a while), for example Runescape. But I stopped playing it for two reasons:

(a) A player can and must develop every skill.

(b) It doesn't run on Linux.

What MMORPG did/do you enjoy? Perhaps Runescape, too? Or maybe WoW?

Greetings Peter
