If you want to make it about exclusives, say so in the title.
Or do you think it's a coincidence that virtuall all of the posters picked games that were exclusive to their console of choice to be the top holiday seller?
The way I see it, it's not about exclusives, but you can't just combine multiple versions of the same game. And there's no way Guitar Hero 4 for the Wii or the 360 will sell as much as Gears 2 or Wii Fit. Combining all versions of Guitar Hero 4 wouldn't be fair, now would it?
