Games that are cross-platform usually play better on Xbox 360 than PS3, possibly due to the fact that they were developed for Xbox 360 first and then ported to PS3. (I have games such as Assassin???s Creed 3 and Tomb Raider both on Xbox 360 and PS3, I know.) My main console is Xbox 360 even though I play PS3 a lot for the exclusives.
