Thanks for your reply.I do know what you're talkin'about.I've unlocked incest and some other skills.I managed to change the secondary interests but the change of AT is still a mystery to me.For the most part your skills aren't directly related to progressing with characters(incest needs to be unlocked if you want to get scenes with a family member though). Progress with individuals is primarily locked behind ATs. If you don't know what I am talking about play the tutorial. I'm not going to get too detailed, but basically you will need to talk to people using specific topics many many many times before you get to most of the scenes.
This is hands down the most difficult game I've ever played and I've played literally hundreds of them.Thanks again for your time.
