Theoretically, where could one get the game data?

I meant in the sense that will distros as a whole drop support for games that use 32bit packages? Will proton and wine stop supporting 32bit games, etc etc

My question was predicated upon the fact that Steam is a market mover, and what are the downstream ramifications of this transition.

What does this mean for GOG games? I have some old games that I’m running through Lutris.
