My steam deck is still regularly used. I can’t say the same for my switch.
It’s just so versatile in what it can do, since it’s a PC at its core.
And being able to play a vast majority of my library, then pick it up later on my main PC if I wish is a huge bonus.
I love relaxing on my couch and still being able to play.
Plus there’s barely a reason to use a switch with how well yuzu runs. And come steamOS 3.5 and its SMT fix, yuzu will run even better.
I haven’t really used Yuzu, mostly because I don’t know where to get switch games nowadays.
I’d say if you intend to use it as a portable PC (as in, bringing a keyboard and mouse, or even using it with an external monitor as well), then it can play simcity or civ well.
If you’re intending to just use it as a handheld, then no, the Witcher 3 would be a better style of game for it. Touchscreen just isn’t the same for a mouse-heavy game.
