I liked Daibanchou and would recommend it if you are looking for games roughly similar to Sengoku Rance. The depth of the story is more than sufficient for this kind of game. Game mechanics are absolutely okay and can be quite challenging during 1st play-through. Characters are plentiful and often have some accompanying events to flesh them out a bit more. Sengoku Rance and Daibanchou have a different gameplay focus, though, and in all honesty you cannot compare their mechanics too much.
