I hate when a PC game is ONLY available on Epic Games store
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.
One reason is Valve has put a fuckton of effort into linux support. So for linux users, buying a game on Steam means it's probably going to work right out of the box. Buying from Epic, it's a crapshoot.
For example, I spent hours trying to get Red Dead Redemption 2 that I had bought from Epic to work. Never did, something with rockstar launcher compatibility. Gave up and bought it again on Steam, worked the first time I hit play.
