Part of the problem with QL's success, is that so many of us are individualistic. That means, we might prefer being outside of the mainstream. It's difficult to make something a 'business success', when it isn't in the mainstream. Being individuals, naturally, we prefer duel.

The solution though, is simple: team-games. In something like TDM, you have exact opposite of individuality. And that's what it takes to be part of the mainstream. A game like SC works, because even though individuals are playing, it creates the illusion that it is actually a team-game.

And just because team-games are what we need for Qx to be business-successful, it doesn't mean we have to sacrifice duel. This isn't the Bible. One of the great aspects of Quake, in its many incarnations, is that we can choose many different gametypes.

Keep duel, but possibly make TDM (or some other kind of team-game), the main attraction. That way, we have a mainstream appeal, and we can retain our individuality.
