I think this is very deliberate. Having played at least a chunk of all 50 games, there are only two or three that I think would have benefitted greatly from more instructions or tutorialization. Figuring out how each game works and being surprised when you find a new way to use the very simple controls is part of the experience.
It’s gonna be way less hassle to just use Linux. The gaming situation is so vastly improved from 6 or so years ago, and the vast majority of games just work, with a large amount of the rest only needing minor tweaks.
The big exceptions are in competitive gaming, and even there it’s pretty much limited to proprietary & intrusive anti-cheats that I wouldn’t have installed on my Windows computer anyway; Riot’s Vanguard and FACEIT are probably the two big ones. Also Fortnite – even though EasyAntiCheat does work fine with Linux, Epic has chosen to explicitly not support it. If you do play one of those few games – or use other proprietary software like the Adobe suite that also won’t work – a dual boot should be fine, it only takes maybe two minutes to swap over and unless you have two beefy GPUs you’ll be limited in a KVM setup.
