Thanks!  I've dabbled with alot of MMOs, but the only ones I've spent a huge amount of time on were WoW and Star Wars: The Old Republic.

WoW had the playerbase that always made it easy to find RP.  The Old Republic was kind of a great extension to the KOTOR games, so it was fun to kinda just treat it as single player if you were having trouble finding stuff to do with others.

Alot of Korean MMOs were fun to play when they launched, but they're also super grindy.  they can be fun for a few weeks before you get bored, imo.  If you have a good group of friends that like to hop from game to game they can be fun, not too sure what the state of the market is like these days is though... D:
