For the most gamers I know games are available on Steam or the high seas, especially for me that use Linux so Epic games are not officially available, every game that only releases on Epic for me it’s a “too bad, I would have bought it”
Yup, I’ve never spent a dime at Epic because they don’t support Linux. I’ve bought games from Steam, Humble, and GOG because they do, and I spend far more on Steam because they support Linux better than the other two.
It’s pretty simple for me, if it’s easy to get on Linux, I’ll buy it. If not, I won’t.
