And this is one of the main reasons I refuse to support Steam. It's all well and good to stop supporting the client, but not being able to play any GAMES you purchased through Steam is absolutely nuts, especially if those games are golden oldies which run perfectly well on XP and will not be receiving any other updates (F.E.A.R., Morrowind, etc...). What's to keep them from shifting to this kind of garbage with Windows 10 builds in the future?
