I'm looking for some lengthy VNs on here.

Got any recommendations?

Also this is off-topic but why is there Ideology in Friction Append when you need the base game (which I wasn't able to find)

Thanks

1. The Fruit of Grisaia

3 Games from the same series. Perhaps even connected but i am not 100% sure.

Other series games like Corona Blossom and Neko-nin, Nekopara could be what you are searching for.

Seems one of those games has controversial tags. If so, you need 15+ posts in the forums and have to put the controversial content filter "on" under "my account" -> "Settings" -> "Account Settings" -> "show controversial content"
