Steam

That's pretty cool! If you don't mind me asking, how are you doing the migration? Last I've checked, most games on steam are sold on there & perhaps other consoles & platforms, but rarely as a direct download from the publisher/dev. The only ones that come to mind are Factorio & Starsecter. So how are you building that library?

Unless your using GoG, itch (which would be limiting I'd think), or piracy (which from another comment you implied you weren't doing?), I don't see how this would be practical.

Not trying to throw shade, just really curious.
