considering that one just sells games and the other sells everything. Because of that, I think the average person going into each store is different andwould therefor buy different games. I would guess more "kiddie" games are being purchased at Wal-Mart since more people shopping there likely have children.

Yeah, I'm curious about their projections. If they just guess that a huge retailer like Wal-Mart is having sales in line with Gamestop, and those numbers aren't in line, it could greatly skew the data.

I wasn't saying that VG Chartz was doing anything "better"; those guys are kinda like Patchter in that they're just taking guesses based on a number of factors. I'm just curious about that 40% the NPD doesn't cover and what techniques they use to get them.
