It's a visual-novel with a nice RPG aspect. And the main goal is to conquer Japan during its "Sengoku" period. Actually its a parodic vision of Japan, a lot of anachronisms, historical characters are sometimes represented as weird animals (Ieyasu Tokugawa is an obese racoon dog...), or they switch genders compared to the original for... scenario matters, I let you imagine why ^^ (like the legendary Uesugi Kenshin who becames a girl in Sengoku Rance). These aspects are quite fun.
But the best thing in the game, it's the main character, Rance. This huge contrast between him and the world were he arrived, coming out from nowhere (from the future perhaps), that's just awesome. His personal goal is just to have sex with every single woman in Japan, but he becames in charge of the Oda house, because Nobunaga Oda got sick for a mysterious reason (~~no~spoil~inside~~)... So Rance has to go over his sex appetite and to unify the entire Japan, by gathering troops from other regions, fighting the other lords and resolve a weird national conspiracy linked to Nobunaga's illness...
I found the background music pretty nice too, especially the world maps ones!
Everybody should try it, check out Google and get its English patched version!
And be warned, that's for adults only, of course
