Old games with deep discount, emulators, strategy games, first-person-shooters, MOBAs, MMOs, etc. That's the stuff PC is good for, new AAA single player gaming ain't it for PC, maybe one day if it overcomes how shit DirectX is.
The Steam Deck is great for what it is, but it's not the place to play TLoU Part I, that will only do the game a big disservice. That's how we get the morons going on about how they don't get the hype for Sony games after experience a terrible low quality version on a portable.
