What Microsoft has been saying about Xbox lately strongly implies that this is a Windows handheld designed to solve software and user experience problems with using current Windows handhelds. And signs are pointing toward the next Xbox console coming sooner than the next PlayStation and essentially being a PC running a console version of Windows. Some speculation on my part, but I’m not the only one coming to those conclusions.
They haven’t really had a history of making you purchase them again. If you’ve got them now, you’ll still be playing the copies you already bought.
Halo has been released on Xbox, Windows, macOS, Xbox 360, Windows Phone, iOS, Xbox One, Arcade, Xbox Series X|S. Then there is the Master Chief Collection which resold the series all over again.
Microsoft will happily sell you the same thing over and over and over. But luckily for them they have fanboys like you ready to defend the multibillion dollar corporation from jokes like mine.
Those are supported platforms, yes. Many of them are redundant because the same license gives to access to the game on multiple platforms. I’m not defending them; your joke didn’t land because they don’t typically make you buy the same games over again. I’m a Linux fanboy and don’t own a Series X; I have no reason to defend Microsoft. Just make better jokes next time.
