Really enjoying this game on the switch. Does anyone have any other recommendations for games like this set in a historical period?

If you mean a scrupulously accurate historical first-person RPG, then no. Kingdom Come pretty much stands alone there. But if you mean games that put a substantial effort into siting themselves in a historical period, then as the kids say: "I got you fam"

In no particular order:

-Expeditions: Rome & Expeditions: Viking (Tactics/RPG)
-Mount & Blade: Warband, Mount & Blade: With Fire and Sword, and Mount & Blade: Bannerlord (Rpg/Simulator)
-Legends of Eisenwald (Tactics/RPG)
-Betrayer (Horror/FPS)
-Hellish Quart (Fighting)
-Medieval Kingdom Wars & Renaissance Kingdom Wars (Strategy)
-Manor Lords (Strategy/Building)
-Knights of Honor II: Sovereign (Strategy)
-Total War (Basically the whole series before 2016) (Strategy)
-BEAST: False Prophet (RPG/Tactics)
-Voor De Kroon (Tactics/Simulator)
-Felvidek (RPG)
-1428: Shadows over Silesia (Action/Puzzle)

That's just stuff on my radar. There's whole genres I don't play, and I kept it to just pre-modern Europe. There's a million modern historical games and a million Chinese/Japanese history games.

Kingdom Come Deliverance 2 will be the only other one, when that one comes out.
I'm feeling quite hungry, might need to play some more KCD.

I had fun back when only the demo was out, trying to do as much as I could before the.... thing happens that ruins Henry's day.   In the full game I managed to level up herbalism so high by picking all the plants in town, even managed to get +1 strength from "leg day" perk, really fun game.  The woods & copse feel so real, like you're walking through real wooded areas, its amazing I wish more developers would learn from what KCD did.
