When I first played Rollercoaster Tycoon 3, I had trouble with creating coasters that didn't make them vomit. Still funny to watch though. Now even after a looong break, I can create epic rides that have low nausea and high excitement. A newer pc (for me) also allows me to ride them without any issues. Watching the swarm take to a newly open pool never gets old....and slides, so much FUN!!!
