AC06 multiplayer did actually do really, really well the only problem was that the game had about 6 months to a year in Japan before it came to the west. Therefore with bonus special planes which added inbalance and other players who had played it for a good few months first the multiplayer became a matter of going online and getting owned for the new players in the west who hadn't had the game for months. Unfortunately the game was not designed with a ranking system in mind of this inbalancement. In the end AC06 was a massively enjoyable title for the 360 which did have a very good multiplayer idea the problems came with staggered release dates, special access codes for content ect and for some players who might not have been able to grasp the tactics there was complaints about the "High G turn and missile lock maneouver" which basically meant turning the plane at the most extreme risk angles to acquire a lock on and fire before an opponent even realized they were the target.
