Mark,
The majority of players of
any computer game, even strongly MP ones like the various FPS and RTS play in SP. The ratio of MP to SP players on forums is typically a bit higher than the overall figure for a given game, because the sort of players who socialize (MP) are also more active on the Net in general as well. That said, I doubt that MP players of Dom 2, even on this forum, outnumber those that play in SP. Especially if you add in the forum lurkers.
EDIT: someone should do a poll on:
* SP only
* MP only
* mostly SP
* mostly MP
* don't play, just lurk here
