Cheapshot: Good Old Games (as long as our proprietary software functions)
False. That's literally the point of GOG. You can download the games directly from their website, install them, and run them without running any GOG software. GOG could vanish tomorrow and you'd still be able to play every game you purchased, as long as you backed up their installers somewhere.
I appreciate the first party reference and backup, but I'll stick with this for the consolidation.
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.
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.
