There are many Windows Phone games in the Microsoft Store, but most of them don't run on Windows 10 PC's unless the developer has built a specific version for it. This is unfortunate, as it means those old Windows Phone games you used to play can't be played on PC.
Our community has wondered whether or not Microsoft should make some kind of emulator for Windows Phone games that would allow those games to run on PC, kind of like how Microsoft built an Xbox 360 and Xbox Original emulator into the Xbox One. I personally think this is a silly idea that isn't worth putting any resources into because Windows Phone games are, well, phone games.
Nobody wants to play phone games on a PC, and if you do you are in a big minority. I would much rather Microsoft put resources into building native Windows UWP games rather than building an emulator for old ones. We'd love to know your thoughts on this however, so make sure you join in the discussion on our forums!
