I voted 3, but looking back I will revise the vote to 4.
I like pretty much all your games. In no particular order I especially liked Roadtrip, Divorced, and CCTV; I also like the really old games(MF, LM, etc).
It would be interesting to see a sandbox game set in a house. You the MC living with mother and sister, and sometimes your friend will come over to sleep after certain criteria is met. Could have things that turn the story one of two ways, such as the mother asking you to help her wash the dishes, you can, or refuse and refusing will make your friend offer to help. You could have the CCTV system running on the MCs PC and at night his friend sometimes sneaks out the room, and will be in different places in the house. Such as watching porn in the livingroom only to be caught my the mother or sister, spying on mother or sister in shower, or sneaking into their rooms.
Whatever you do I will buy it anyways, as all your games are good.
