mario kart and wii fit have to be a solid kick in the teeth to sony and microsoft. Those games have been out for several months and they're still topping the charts. The negative of the wii is supposed to be its low selling software but the shelf life on some of their games is getting ridiculous this generation.
Little kids mostly I guess. When they had a tour at UCLA for middle schoolers, pretty much every single one of them had a DS. Nice to see Force Unleashed take 3 spots in the top 10.
It seems like little kids seem to break/lose their DS all the time and parents just buy them another one to shut them up. It's a cray money making cycle for N.
