I can attest to this first hand. I usually do better on teh PS3 version of BFBC2 than on teh PC version. I just assumed that PS3 players were not as good at it. But I think teh mouse may have something to do with it. BTW I posted this before reading your links Pain so I will go back and do that now.
Maybe I don't do teh best on BFBC2 sometimes though cause I drink too much when I play.

EDIT: After reading your links I agree that retailers are probably going to be going slowly out of games in teh gaming industry in yrs. to come. There are people that are always gonna want to be able to buy a "boxed" game though. So who knows how soon that will happen. As far as console games I think it will take longer for that transition as teh developers of teh consoles will have to put much larger HD in them. I'm sure this will be teh case with teh next batch of consoles in a few yrs.
