I got your Sims tragedy beat all to hell.
I’ve been playing Roller Coaster Tycoon and I just had 16 people die in a fiery roller coaster accident.
That’s too quick a death for the little buggers. You want evil, try this out.
Make yourself a lake. Bridge over it with as much walkway as you can muster. Once it’s nice and filled up with wandering guests, start deleting sections of walkway. They all fall to their watery graves. Bwahahhahahahahaahhaa.
Actually, my daughter has been building lakes, picking up random guests and dropping them in to watch them drown.
I don’t know where she got that attitude from. 
Sometimes when I’m in a bad mood I dig a big hole in the middle of the park and drop all my guests in. They get madder and madder, but they don’t die. Then I kill them one by one. I put as many dancing panda entertainers in as I can afford. Dante’s ninth circle. Bwahahaha.
Also, on the subject of fiery explosions, I accidentally discovered a few horrible death methods. Have you tried building the bobsled coaster yet? I had one up and running, all cars full, and there was some kind of secret malfunction. Cars started flying off the track and into trees and other rides, one car after another. I killed the coaster riders a few at a time, and even managed to crush some poor bastard on the car ride. I tried to rebuild it so I could shoot bobsled cars through a loop on a nearby coaster, but I never got the aim quite right.
psst - Euty, if your park rating goes down, try drowning the angry guests. Your score will go back up, and they won’t be around to break benches and lamps.
Only 16? I regulary accidentally kill 32 and more. I get frequent station break failures.
Has anyone buried their guests alive yet? Good times.
When a customer is red with anger, I will put him in time-out. I lower a square and drop him in there until he mellows out.
I have found if you buy the shuttle loop and change the launch speed you can shoot a train full of people off into the park.
i always liked playing the sets with little towns you have to build around, and then creating a track which launches a train into the town at 70MPH. aereal bombardment!
