I usually buy games with heavy discounts or in bundles. For example, the last bundle I bought was Skyrim Special Edition + Prey for under €20. I was OK if one (or both) were unplayable or I if simply didn’t like them.
I don’t get upset if once in a while a game does not work, because I’ve seen the evolution of gaming on Linux since the 90’s, and have seen many unplayable games become playable. Yes, it sometimes takes a decade or so. :-)
I don’t spend too much on games because I have too many already that I most certainly will not be able to play before I die.
You’re free to spend your money however you wish, but buying a whole bundle and being OK with not being able to play any game in it? If you would wait for the 10 years until it actually becomes playable you’ll probably be able to get it for even less than $20.
You do you, but I personally don’t advise people buy something until it’s actually working. “Sit on this for 10 years and maybe then you’ll get what you paid for” is bad advice.
