The issue here is that this is an existing "standard", by the logic of the comic. I wouldn't be surprised if there were already unofficial Linux ports of this launcher to begin with.

Also, even if it was fragmentation I'd prefer competition to ensue. I don't want another Steam situation, even if in theory a launcher isn't holding any valuable data hostage.

Eh, I don't need the comic to be a perfect fit.

It's not a port, but Heroic is an implementation of the GOG ~standard~ store as a Linux user. I will use it until I can't.

Why? Precisely because of what you say: I don't want another Steam. Heroic does others like Epic, too; open consolidation like this is my ideal.

I'm not really against GOG taking a swing. I'm comfortable calling it a reference/backup, but I do prefer something like Heroic.
