While I understand ioi's point and think the McDonald's to the gourmet burger is a great analogy, I think there are some issues. While I think the site is great in everything, and come here at least 5 or 6 times a day, I have trouble with one concept.
I don't know if the VGChartz press team is misleading them or not, but the article makes a good point that newspapers/media citing vgchartz are in a sticky situation as they are referencing numbers that may be very rough estimates (a la MGS4), especially when those numbers may change days later. I don't know if VGChartz is somehow contacting these papers and giving them the wrong impression, but if they are, I think that's wrong.
I think VGChartz is great for what it does and I appreciate all you've done to provide us with information. I just hope the site's not misleading other press to get more promotion.
