Where did I ask anyone to do anything? Do what you want with it. Preferring a platform that isn't held together with duct tape is hardly being a 'fan boy'. It's well documented the windows store is a total mess with broken releases and constant storage/download issues.
Is there any difference between the quality/graphics playing on a pc through Xbox or Steam?
you ask people to pay 50% more just to play on certain launcher ... fanboy much?
Rather spend the extra few £ and get it on steam https://www.cdkeys.com/greedfall-gold-edition-pc-steam
