That won't be very helpful though. The OP has specifically had issues with Epic not including universal controller support, and the situation with Microsoft Store is even worse.I should mention OP that Outer Worlds is available on the Microsoft Store.
While Epic is a pointless extra launcher with less features, Microsoft has actually implemented "features" that are bad to you. Microsoft locks down all game folders with their terrible DRM scheme and prevents you from modifying all game files. You can't even run game exes directly which prevents adding them to Steam easily. By default you're even prevented from LOOKING at the files although that can be bypassed. It's like a nightmare version of Denuvo DRM.
