well that first link could be from the very first day of vgcharts (or at least the first week)
The first time I came here was December 06, but it looked nothing like the blue boxed version shown in the links from late August onwards, so ioi must have changed it for the Wii/PS3 release.
Seems the style changed in August twice, the second time (click on Aug 25) was when the forum was introduced... with threads made by Broshnat, Joni and Luthor.
Can I ask what was the "select your region" box about (see late August and September links) I assume there was a world map under there at some point but what did it link to?
