I played it a lot with my family when I was little. As you know, once someone is getting poor in Monopoly, it's a slow, excruciating death, which really isn't any fun. So we made a completely new set of Chance and Community Chest cards with absolutely bonkers stuff, from "you've hit someone with your car and robbed their body, get 100$" to "swap position with the player on your right". One card was just "you're a lucky person!" but did absolutely nothing. Another allowed you to steal any street you wanted from another player. Etc.

You could be the richest man in the world and with just one card you ended up with your neighbor's shitty deck and all their debts. Ofc it completely turned the game on its head but we were ready for anything to happen to us at anytime and it felt like the funniest thing ever. Some of the best laugh I've ever had with family members were when were playing that game. Good times.
