How do you make a computer game not work?

My dad is always playing Tropico on his computer and when he gets off he is in a really bad mood. My mother and I were going to delete the game but we knew he would blame us. How do we make the computer game not work so he will stop playing it? He does know a fair bit about computers so it has to be hard to fix. The game is from steam if that makes any difference.How do you make a computer game not work?
That's easy. Delete one file from the game folder and replace it with a fake one. That way he wouldn't notice you have deleted some files there. Or have your firewall block it...How do you make a computer game not work?

edit some of the coding of the game and delete important sections of it. If you know more about coding then you could also rewrite some of it to perform the incorect functions.
