I don't know how many times I've said this but I'll say it again. VGchartz does NOT cover everything from everywhere. they only get data from NA, Europe, and Japan.

VGC does cover world wide

Depends what 'cover' means. Don't VGC only get sample data from NA, EU and JPN and use it to estimate the rest?
