Considering how many Dreamcast systems there are in the world, there probably aren't all that many people who would buy it, imho. Even if you think all Dreamcast owners would buy it, there are other people who honestly don't care about Gran Turismo 2 (ahem, like me). And of course people who already have a PSX are much less likely to go for the single game pack. I could be wrong, but we'll see...
