If I had had the choice to pick it up for either console, I would gone with the ps3 version; why would you want to go through THREE discs? Yeah sure, you could be one of those gamers who cared about the things just mentioned above like gamerscore, but it doesn't make sense otherwise. I had only a 360 at the time and never felt the need to get a ps3 because there was nothing compelling enough for me to get one. Before it was announced that 13 would not be ps3 exclusive, I did consider purchasing a ps3, but after the announcement and because of the ridiculous price of the ps3 at launch (AND it's lack of interesting games to me) I had no more need for a ps3. Those are days long gone by, but as mentioned above, it most likely comes down to not having a ps3 available at the time.
