I've played Ryzom. Prolly gonna come back to that eventually. It was some good shit.
I played AoC for a while. That game had potential and pissed it away. The roleplay community on my server was alternatively either gold or squeezing wedges of lime into my fucking eyes. Might go back and try the PvE servers.
Played a bunch of other shit. NWN2 servers had some half-decent roleplay, adaptations of Fallout like Fallout Online were interesting, old Ultima Online servers were a lark for a week or three. I've read about, investigated, or done the trial on upwards of two hundred MMOs, mostly free to play stuff and mostly not doin' the trial. Not WoW, though. Fuck WoW.
I am a fan of the stuff Three Rings churns out, though I'll be waiting for something nice to come out of Whirled before getting in too deep; I hope to find or run a nice server for SWGEMU once they get in-space combat up and running, and I want my Black Prophecy and Jumpgate: Evolution now plox.
Otherwise I play Dorf Fortress, Crusader Kings, Mount & Blade, and sowan. Been thinking of doing another Planescape: Torment run-through, or trying out Freespace 2: SCP or something. Maybe finding or modifying a nice sci-fi 4x gaem.
Oh, and KoL was fun for a while.
