I was playing Halo 3 over the weekend and it still had nearly 17K people playing it. Close to 5 years of being out and it's a little less than half of Halo 4's players.My god, Halo 4 barely scratched 400k at it's best? How the mighty have fallen. I remember Halo3 had over a million at peak in September '07.
:/
That is assuming the counter is not broken, of course.
