Microsoft's Universal Windows Platform, or UWP, approach isn't sitting well with many game developers. Four months after criticising UWP ecosystem for being a walled-garden, curtailing "users' freedom to install full-featured PC software, and subverting the rights of developers and publishers to maintain a direct relationship with their customers," Tim Sweeney, co-founder of Epic Games, the studio behind the Gears of War and Unreal franchises has once again lashed out at the Redmond-based company. He alleges that Microsoft plans to make Steam -- the world's largest PC gaming platform, "progressively worse and more broken." in a move to bolster people's reliance on the Windows Store. From a Gadgets 360 report: "Slowly, over the next five years, they will force-patch Windows 10 to make Steam progressively worse and more broken. They'll never completely break it, but will continue to break it until, in five years, people are so fed up that Steam is buggy that the Windows Store seem like an ideal alternative. That's exactly what they did to their previous competitors in other areas. Now they're doing it to Steam. It's only just starting to become visible. Microsoft might not be competent enough to succeed with their plan but they are certainly trying," Sweeney said. He adds the outcome of this would be forcing every app and game to be sold through the Windows Store alone. "If they can succeed in doing that then it's a small leap to forcing all apps and games to be distributed through the Windows store. Once we reach that point, the PC has become a closed platform. It won't be that one day they flip a switch that will break your Steam library -- what they're trying to do is a series of sneaky manoeuvres. They make it more and more inconvenient to use the old apps, and, simultaneously, they try to become the only source for the new ones," he claims.
