This is even worse in the mobile space and is part of why I don't buy any mobile games and avoid apps there as well. In the many years of owning my iPhone I've had apps just disappear from the store or no longer be able to be downloaded due to not being updated for the latest OS. Apple backwards compat generally sucks compared to Windows, especially on iOS it seems. Consequently I buy very very few apps on mobile. With Windows, if I had to, I could potentially run an old game in a vm of an older OS. Or you have things like DosBox which lets many much older games be played. With mobile that's not really feasible. Even if I could run a VM on my main computer the experience of trying to use it would suck and is completely different from running it on the phone itself.
