Nothing more disappointing to me than seeing a game I might enjoy... and then it's only available on PC on Epic Games store. Why can't it be available on Epic, Xbox game store and Steam? It's so annoying, like you have no choice but to use Epic... which I would literally do ANYTHING not to use.
It also sounds like a cheater's paradise.
What do you mean by 'cheater'? Like 'scammer'?
Like people who would otherwise get banned from a platform for cheating in games. Tracking that down is so much more complicated/impossible with federation. In other words it makes ban evasion super easy. See also: email spam.
