You're kidding, right ? Dual Family a realistic slow burn game ? With skeletons, piano, airport, Madonna and I don't even know what type of stupid fuckery in it, you like this game ? I know there's no accounting for taste, but still.
I think Deadmoon Survival and Elvensang are the ones that could really be to your liking. The slow burn incest between mother and her son are done really well here.
Also check Away from home, it could be to your liking.
