Lots of other games featuring Rance as the central character. No more "Sengoku" Rance that I know of. And I don't think any of the others have been translated, either.
If you like the scope and strategy of Sengoku, and if you can handle the langauge, you might enjoy
Kichikuou Rance. It's a little old these days, but still a lot of fun to be had.
