Cloud gaming is definitely the future, I stuck a oldish amd video card in my server and use it for plex transcoding and steam headless so van play a decent amount games on my phone anywhere I have 5g, I hardly turn on my gaming desktop anymore and opted for a thin client laptop.
self hosted cloud going you might be right. But I'm currently forced to use geforce now to play fortnite with my wife cause Epic hates Linux and goddamn is it a miserable experience.
