First off, I enjoyed the fuck out of Sengoku Rance, although it can be hard (gameplay) as hell for new comers. Second off, these games involve a shit-ton of rape... Piled on with more rape. So, if stories involving rape of fictional characters offend you... you might want to stay away.
Inferior to Sengoku Rance but still pretty cool. I like how the map is rather larger though. It feels like it takes more time to conquer all...at least to a point.
