Hi,
I know from a fair while back, the bestsellers list on GOG worked in one way, then i remember someone mentioned they changed it. Anyone know how they work it out now?. Is it daily?. Weekly? . Noticed there were two $100 +AUD games on the list yesterday (Metro Franchise bundle was one - its like on the 3rd page now but was high as 4/5 th?. The other one was Bloodlines 2 Moon edition).. surprised me.

I think the bestselling list on the frontpage is about revenue in a certain, short time span (I don't know how long it is exactly). That's why it has quite expensive games on top most of the time. The all-time bestselling list in the shop is about most units sold though. You can see it when two game enter the shop at the same time and after a while the more expensive one is in front in one list, while the other one is in front in the other list.
