Before I go on, let us avoid any petty PS3 vs XBox 360 debates. Both consoles have their perks and each is geared towards a different sect of gamer. Just please just answer the question honestly and without opinion, just facts. Now to my response:
I havent owned Skyrim in a while, and last I played was on 360. Had to get rid of the 360 and the game (still very saddening), but am about to invest in a PS3. Any differences in the game system wise? PS3 get any cool stuff the 360 doesnt/vice versa?
I am a PS3 player and I've played it a bit on 360. The difference is simple. XBox360 has the DLCs and Kinect stuff. Otherwise it's the same except the triggers are flipped top-bottom. To better explain, here is a trigger translation chart
L1 = LB | R1 = RB
L2 = LT | R2 = RT
On XBox the triggers are:
LB = Sprint | RB = Shout/Power
LT = Left Hand/Block | RT = Right Hand
On PS3 the triggers are:
L1 = Left Hand/Block | R1 = Right Hand
L2 = Sprint | R2 = Shout/Power
I actually prefer the PS3 set up. However if you want you can change this in options.
