As there never has been a non-pack-in at 50 % or higher, I would say 40% of the biggest userbase is very good.
If Wii > Ps2, you only need a 10 % rate to beat most on 360 and Ps3. The best Ps2 had was 12.5%
I guess NO WII GAME will sell more than 20 % in the long run. SMG will end up at around 10%.
"Trust me... if we were 12 year olds trying out Mario galaxy for the first time we wouldnt give mario 64 a chance."
Change it to 14 year olds, and I'll agree.
