Well, sad to say, but Microsoft has pretty much "banned" Steam on windows 8. They have a new Game Marketplace on there they they want you to use, and they have made Steam illegal on it. Not only is this ridiculous, but Steam is the PC gaming HUB. Plus, Microsoft's Game Marketplace sells for 2 times the Steam Game pricing, making it stupid. Not only this, but VALVe (the maker of steam), I guess you could say is a third-party publisher who broke off from Microsoft in the Nineties. Is Microsoft trying to persecute VALVe on this?
Please share your opinions on this, this is a bad situation for PC gamers.
[EDIT]: Apparently Microsoft has unbanned Steam. Not only from my sources down below (Danke to all of you), but also from more recent updates on this issue. However, It is still a problem for most upgraders, as your downloads glitch after an update to where you have to re-download the games. I know of several people who upgraded who faced this problem. (I'd say the glitch comes through 1-10 upgrades, maybe?)
