I'm not good enough at RTS to play multiplayer. Actually, in general I only play single player games. I don't know anyone IRL who likes the same games as I do, and when and how I play games isn't very conducive to scheduling. The last multiplayer game I played was Diablo II, with my brother; our schedules eventually got out of sync, but he kept playing with the same character, so eventually there wasn't any point in me even trying to catch up. I've tried to interest him in other RPGs, but he only plays Diablo (or Minesweeper).
