Halo is big enough that even if you didn't play it because of your personal system choice, you know what it is. It's more than likely that the majority of people on these forums have probably played it before even if they are PlayStation owners. Saying that Bungie doesn't have as much rep for the PSN side doesn't hold a lot of water. Oni, a game made by Bungie was only for the PS2 console (console, because I know it was also on the PC). Xbox players aren't feeling left out, many, not all, are feeling shunned because of some apparent bad blood between Bungie and Microsoft that does nothing but damage one of their user bases.
