[quote]Assassin's Creed crowd AI differences on 360/PS3 debunked
by Ian Stanfield
IGN recently published a preview on the upcoming game Assassin's Creed, stating that the Xbox 360 version of the game would have more advanced crowd AI than the PS3 version - due to the improved threading that is attainable with the 360 development hardware. IGN cited discussions with the producer of AC, Jade Raymond, as a source.
Apparently it was all a severe misunderstanding, and that there are virtually no differences between the two games, save for Live Achievements. What Jade Raymond meant to say was that the methods for developing the AI is different.
UbiSoft stated:
"While the method for distributing AI load is different on each platform, the AI code itself is the same. Players will experience the exact same crowd results on PS3 and Xbox360."
