Wii Fit continues to be the number one seller last month, as it looks like practically all those casual parents that bought a Wii last month bought Wii Fit as well. Street Fighter IV debuted pretty strongly, and surprisingly, even though the 360 userbase is double that of the PS3, the sales numbers are quite close. That 360 controller just isn’t good for fighting games apparently. Killzone 2 also makes its debut at the number 5 spot. I would have expected it to sell more, considering it’s an exclusive PS3 title but I honestly don’t know even what the userbase is even made up of for PS3 owners – maybe half casuals and half hardcore? Mario Kart & Super Mario Bros for DS continue to sell strongly as the DS keeps selling like hotcakes, and wow Guitar Hero World Tour still up there in sales for the Wii. I guess it was off to a slow start but it’s probably what’s saving the Guitar Hero World Tour games right now.
