Been playing through this game and I have to say, the story and design of this RPG is extremely good! The only downside is that there is very little sexual content in the game. If I would have to guess, it's more on the line of 90% RPG and 10% erotic content with most of it coming at the tail end of the game. It took me about 4 hours to complete the whole entire game and there is only one kissing scene depicted, but it's a dick kiss scene instead of a face kiss scene.
If you like your erotic RPG games with a lot of story and adventure, I would highly recommend picking it up. If you're just in it for the content, I would hold off for a while and wait for a sale or until more content gets added in (if they so choose to do).
