There does come a point where there isn't much else to do with the game once you get good enough at it, so I started having fun doing "experiments". One of the things I did in RCT was build "prisons" where I leveraged things like the carousel to work as a one-way door into the park to allow guests to come in but prevent them from leaving; it lead to a barren cement building with a turbo drop coaster designed to be intentionally dangerous so I could "execute" prisoners. There was puke everywhere after a while. What a disturbing mind I had.
