If you had asked this around 2010, the vote would have gone much more heavily towards CE and 2. This is certainly interesting to see the shift as the community now grew in from Halo 3 and Reach. Many of the old-timers have moved on, and the septagon changes. I recognize this having started off during the time of H2, but having actually started my Live career on H3 I'm much more partial to the memories of 3. This sort of thing could make a great anthropological study of gaming society.
