Dev: I'm gonna be a dick and make false equivalences because I personally am not affected by product $X not supporting $Y

But the two major differences between what you are talking about and what others are talking about are that a) we have the hardware, it is totally a software issue and b) we are mainly talking for software we already have paid for, not software we may or may not buy in the future.
But hopefully as Linux becomes more popular with gaming (and Microsoft is distracted with UWP and the like), Wine will also see improvements that make gaming better. Already since Valve shown up and rattled things, Wine's gaming compatibility seems to have improved a lot compared to previous years.
A solution for this is to set up dual boot or whatever and use it only for the Windows-only games, until you get bored of them. Then kill Windows and you're free.
And the number of games I'd leave behind in Linux is way more than a simple handful.
