This is stupid move from the game's distributor whoever it is. I can understand why I must pay for Xbox version, because it is clearly another platform. But pay three times for GOG/Steam/Windows store to run game on the same WIndows OS? This is bs. And by the way, for now only GOG's version has no achievements, too bad I discovered it after purchase.
Are you buying three copies of the Windows version for other people? Just pick one of those stores. You don't need to buy a copy from every single store. The GOG version might have achievements added later. Game Features tell you if a game has achievements or not. They're on the right under Game Details.
