I've only used the Epic Game Store because they did the shit thing and bought timed exclusives (Borderlands 3 and Final Fantasy 7: Remake) that I wasn't going to wait another minute to play. Other than that, I don't bother with it at all because Steam is my default.
For that reason, I also don't play Ubisoft, EA or Rockstar games. I'm not downloading another launcher, game manager, whatever to play your games. Fuck off.
