Exactly what I mean. You'll never convince PS loyalists to buy an Xbox even if you put out hit after hit after hit. The next Perfect Dark, Fable, Halo, Gears, etc could all be the greatest games of all time and that'll never convince a PS lifer to get an Xbox.
You start putting shyt like CoD, Elder Scrolls, 2k, Madden, etc on one console and watch how fast they buy Xbox. Hell, Street Fighter has never been exclusive to one console until last gen. They put SF on playstation only and now all of the fans fighting game genre play PlayStation. No one talks about that though.
