This would make a good game.
The player is in a pre-divorce situation. He finds himself in his own loft for the last time. He has a chainsaw and maybe other tools of his choosing.
She who used-to-have-to-be-obeyed “just popped out”, maybe for the last time, maybe for forever, maybe to go meet Chad. You have no idea how much time you have.
If you do nothing she gets the house. The objective is to neutralise the house as an asset by rendering it structurally unsound, preferably fit only for demolition. At the same time you do not want the roof to collapse or anyone to to be hurt lest the authorities take note. You also want to give yourself time to make it clean away, preferably to another continent. This is delayed action or slow motion demolition.
Roof members may be cut through, partially cut through or left alone.
Which members do you cut?
Obviously the answer will depend on the design of the roof.
The only variant to this game I can think of involves water; some kind of slow, silent leak in an inaccessible area.
Meddling with the electrics, the gas supply or indulging in arson mean that you automatically lose. Fungii and moulds work far too slowly. Messing with the lives of people who subsequently buy the house again means that you auto-lose.
