While playing Rollercoaster Tycoon one time, I remember that I was tasked with the mission of getting a higher approval rating than the park next door. Rather than make my park better, I instead built a rollercoaster that launched people at 100mph into my rival’s park. Since technically those people died in my rival’s park, their approval rating would plummet and people would rush to my park and straight into my deathcoaster, which only caused their rating to drop lower and lower. I did this for an hour until the game said I’d won.
