Non-gritty/non-dark singleplayer games I can level grind to with my brain firmly off

No shooters or horror please.

Looked at other grinding threads and a lot of the responses are games with a bleak atmosphere, multiplayer games, shooters, games you cannot turn your brain off to… I did find threads that eliminate one of them (e.g. found a thread looking for grinds you could do brain off) but the other three had a ton of representation.
