| This guy's way off base. The numbers don't work. Even if GTA does only sell 12 million total copies and has an overly slim profit margin of $15 per copy on average, that's 180 million versus 100 million invested. In any other industry that's an incredibly smashing success (a profit of $80 million! I'd take it...)
While it's true that titles with that kind of development cost are few and far between, developers don't commit to that kind of budget unless it's pretty much a sure thing. Think GTA4, Halo 3, or on a lesser level GoW2, anything Final Fantasy, the MGS series, etc...
As far as driving console sales... the only thing driving console sales now, imho, is price. Those who want it pretty much have it. The rest will buy as the price comes down. We're in the middle of the cycle, or close to it. The whole "I have to have the console because of this particular game" thing is over. I don't see his observation as being groundshaking. The Wii is an anomaly. Meaningful in that it influences a broader segment of society than traditional gaming. But it won't totally change the industry toward making more cheap games with lame graphics. |
