Well techniclly they are dating sims, but their lovely technical name is Visual Novel. I've played plenty of them. To many to name here for that fact. Though I will name some good one's that I've played and like a lot!
- Clannad
- Little Busters!
- Planitarin
All these are made by the same company, Key. Ever heard of them? Amazing Visual Novels I must say! Key is just amazing...I bow down to them. I actually have a Visual Novel maker program and have my own in the process of being made it's called Daioryie [Diary]. Story and the art is both by me^^
By the way, all three I named are all ages Visual Novels and not Hentai's. Planitarin is a Kinetic Novel. Which means that no choices are made in which the ending can be altered in anyway.
I'm done ranting now...
