Halo 2. Makes the most sense. It was the game which XG built the community on and even those who left to go play COD games find their way back to HALO from time to time. We have a game night every week on Wed. that has grown and lastnight it seemed to be almost like old times as we started with 3 or 4 people then kept adding some throughout the evening as they go online. Had a huge party doing both customs and matchmaking. Let the good times roll!
This made me lol because its coming from a CoD player. I love CoD, but AW is terrible. It seems like Halo really has no chance in this poll lol. Everyone plays CoD now. Its kind of sad because this community was founded and grew on Halo.
