That's why the sales of Ouendan are only at 60.000. They didn't notice Lik sang and Play asia.
Yeah, there are a lot of differences like that
At vgcharts we try and make adjustments for these kind of things so that sales reflect more closely what was sold via online retailers, non-specialist gaming stores and so on who media create / famitsu don't track and have to estimate for by comparing tracked sales with figures from publishers and so on. In the future we hope to improve this even further!
