Why is this 2 day excuse even used? Doesn't every game launch on Friday in UK? That's a bull-shit excuse.
Legs? I guess we'll have to wait and see on that.
Userbase comparisons? Totally valid. Selling less than the PSP ones, despite having a huger userbase does need to be mentioned. The difference from when GTA: L/VCS launched on the PSP and this game launching on the DS is huge in user-base. What is it, triple or quadruple what PSP was when these games launched? And couldn't muster a bigger opening? That is a big deal.
The game didn't do horribly, and will sell well, but not better than either PSP game (well, maybe better than VCS), and it was said that more people were working on this than on either PSP title, so...
