Well the official answer would probably be no, not at this time anyway.
My view is that we still enjoy Halo, and still have competitive internal scrims, so as long as we can sustain that, we will keep doing Halo.
Branching out into a second game would attract some new people, and maybe help keep some existing members interested longer, but it would also divide the membership we do have and make it hard to get enough people to play either game.
But at some point, if Halo interest keeps dwindling, we'll have to make a call whether we close down or move on to another game.
