That high? Hardly :DEvery guest has his own preferred intensity and nausea tolerance, which you can check by clicking on a guest and then on the tab with his face.The Extreme and Ultra-Extreme intensity ratings indicate a problem with your track. By taking a glance, I see you're not using banks on turns where the train has high speeds. As strange as it sounds, the game tries to follow the laws of physics when it comes to ride behaviour (except when the Merry-Go-Round breaks down, I'd like to see someone explain that :D ). If a train reaches a high speed and approaches a standard turn, the riders' inertia forces them to jump sideways in place, but if you rotate the same turn with banked tracks, the ride will be much smoother.Here's the option to do so:View imageAlso, if you expect a train to have high speeds when approaching a station, you can place speed brakes to gradually reduce the speed instead of having it just stop abruptly after reaching, say, 90 km/h.
