[quote name='grrouchie']360 is cheaper because it came out like 2 years earlier - PS3 versions just dropped recently I think.
Is there anything extra in the PS3 versions? Thinking about picking it up and would like the PS3 version mainly for 1 bluray instead of 4 discs.[/QUOTE]
I heard PS3 version has extra playable character, i think i saw it at youtube game review.
The $18.99 used is not bad, i always buy used from Amazon Warehouse their items are really in mint like new condition.
The last time i bought used item from them is like a month ago Red Dead Redemption for $22.99, and the codes that comes with it are unused.
