As mentioned earlier, one reason for rewriting our pricing algorithm was to handle the extra volume of Mac and PC games. A couple days ago, we added about 850 Mac games and 7,400 PC games to our database. Most of them have prices now. As time passes, more games will have prices and the reported sales volumes will improve.
We know that we've missed some games. We'll continue adding the stragglers as we find them. If you have favorite PC or Mac games that aren't listed yet, please let us know.
Unfortunately, with 7,500+ PC games, we aren't able to fit them all on the PC Games console page. Instead, we added a PC Games search box on that page to help you find what you want. We have a couple ideas how to show a price list, but haven't implemented them yet.
