On a serious note, I come from a private group called The Halo 3 Academy. When we were in full swing there were something like 3000 members, we ended up on Bungie Favourites blah blah The thing is though we had a real community, we played together, we came on Bnet to discuss various things daily, from that time I've actually made some real life friends that I sometimes drink with! The sense of community was like nothing I've ever experienced. I'm a Mythic member now (or was) and I feel like I still post here every day out of habit rather than any sense of community because that is long gone unfortunately.
