Multiplayer means multiple sales for every player that buys a copy. wink

I don't remember if it was after D:OS1 or D:OS2's release, but at some point Swen made a statement saying he was surprised that Larian's internal data pointed towards a majority of the players playing the game in single player mode despite the game mostly being advertised as a coop game. I think the single player playerbase is significantly larger, but the multiplayer/coop playerbase is more vocal since coop mode for this kind of game is a fairly uncommon gimmick for an already somewhat niche genre.
