Awesome game. I was high on cannabis when I played it, and managed to beat it in one sitting about 10 years ago. I want to play it while high on shrooms, that would be even crazier.
The Steam Deck IS a PC though. You can install SteamOS on your computer if you wanted to.
For the purpose of the argument the other user was making, it is functionally similar enough to consoles that it doesn’t feel like a PC, unless you want it to. So really, it suits everyone.
