As powerful as the switch is, I really don't think it's capable of running TS4, at least not in its full form. If even Crash Bandicoot had to be scaled down for the switch in it's look, and the developers weren't even sure it could be done. Crash isn't even CLOSE to as complex as the Sims, especially if we were to do it in the full form like PS4 and XBOX have. Maybe a spinoff type, like the old Sims 2 or 3 games on console? like, a veeeery heavily modified version of the game with a single expansion like Cats and Dogs will maybe work? Even games like the Zelda, Mario and Animal Crossing series aren't exactly graphics heavy. They're simple, but pretty. The Sims 4 ain't simple.
But as much as playing the full Sims game on the go would be, I really don't think it's possible.
