If Bungie went with playstation for Halo it wouldn't have been as successful. The early playstations and PS3 were shit. Xbox 360 was a far superior console at the time and there is no arguing that. I doubt people would buy a inferior console to play one game on it. Bungie made a great game for a great console. If Bungie went with PS it would of been a great game for a bad console. We wouldn't be where we are today playing Destiny, one of the best games ever made mechanically and graphically without Microsoft and the Xbox.
