I can only say that the game sold decently, but well below expectations for a GTA game.
Didn't matter if it was on the DS or PSP, where supposedly the DS has more of a casual userbase, and the supposed hardcore PSP userbase didn't either.
I game. You game. We game.
I'm a videogamer, not a fanboy, but have a special place for Nintendo.
