Except that the experience just sucked. It was mediocre. My biggest gripe is that launching games was really slow, the store was kind of painful in lots of little ways and it was sort of annoying to deal with them in general.
Maybe they fixed those issues but it was too late to retain me. I literally repurchased the games I was still playing on steam which didn't have those issues.
At some point, in the early days, Steam was a bit rough. I remember a summer where occasionally steam would stop launching and you had to reinstall it (back when it was a blocky dark green app). But Steam got over those teething pains and has been really high quality since.
Itch.io is great, I don't use their launcher (just haven't tried it) but I use them and enjoy them. Their checkout experience is fairly sane. It's not as if I refuse to use other platforms.
But Epic just lowkey was not a great platform.
