If the PS3 has 100 games and the Xbox has 100 games, I'd say it was a tie.
If the PS3 has 100 games and the Xbox has 100 games, and 50 of those games were available on the PC, it still wouldn't factor into my decision because I don't have a gaming PC. Now, if I DID have a gaming PC, then the Xbox would appear far less enticing and the PS3 would win easily.
I see what you "exclusive" guys are saying. I'm just saying that, if you are doing a one on one comparison, why can't we do a one on one comparison? I'll say it one more time and then I have to go.
ONE library vs. One library (I didn't say anything about exclusives! in that last sentence fragment, did I?)
