I’ll just wait until the dev caves and puts it on Steam for half of the original price, I’ll pirate it, or I’ll literally never play it.
They can have my money when they put it into the library I’m already bought into, or they get none of it. I’d consider using two libraries of games, if any of them could compete.
Epic Games is garbage and low featured, Origin and Uplay/Ubisoft Connect are slow and clunky. Add this to the fact that I like my games to all be in the same list, and I’ve got very few reasons to encourage the companies running these bad launchers by paying them for the privilege.
This is only maybe true for convenience, maybe, but as far as cost, experience and quality, nope.
