NotLost

I never got too deep into it, but I enjoyed ~10 hours of it before getting distracted by other games. It felt more like a park business simulator like Roller Coaster Tycoon, rather than an elaborate park and ride designer like Planet Coaster.

It's totally worth $15 if you want to scratch that itch.

There's a fantastic LotR total conversion mod for TW: Rome. It was also ported to RW: Rome Remastered, so very easy to play even on modern hardware.

EDIT: Search for Lord of the Rings: Total War (Remastered) for the most recent version of the mod.
