Recently I got it on the PC and I have to say its MUCH MUCH more fun than the console counterparts. Quicksave exists by hitting F5. The game is easier with a mouse which means I can actually hit things I shoot at. The graphics are nicer and the texture pop-in is less noticeable. I'm not entirely sure of all f the reasons why but Rage on the PC is much more fun.
Ill keep the PS3 copy for co-op with friends.
I found the above secret Wolfenstein room. It was awesome.
