I guess I’m not in the majority, but my reason for finally switching fully to linux after 20 years is that gaming finally Just Works (mostly) thanks to Wine and Valve. I’ve been gaming under Linux since Quake III, but always kept a windows install because lots of games ran poorly or not at all under linux.
Last year I finally switched to an AMD GPU, and all the games I’ve played since then worked either OOTB or required minimal effort to fix (I don’t play multiplayer games except for Overwatch, which also runs fine). I haven’t booted my windows install in like 6 months, soon I’ll wipe it to make some room for more linux games.
