NoLimits 2 Roller Coaster Simulation Design it, then ride it

The editor is a CAD-style wire-frame workspace: you drag and drop track, supports and objects, zoom in and out, and shape every element by hand. There are no templates and no starting blocks. You decide the layout, the rail types, the block sections, the brakes, whether trains run backwards or two coasters duel from synchronized stations. Little rods show g-forces and inertia as you work, so you can see when a curve would pin riders to their seats or fling them out of them. The only real constraints are physics and your patience. Finishing a coaster that actually runs is a genuine relief, and then the terraforming and theming start.

Once the track is built, the simulator runs the whole ride in real time, from the train chugging up the first lift hill to the stop on the exit platform. Wind rushes past, metal scrapes on metal, and the physics are accurate enough that your stomach drops as you crest the first summit, even sitting perfectly still. In VR (Oculus Rift and HTC Vive are supported) the illusion is strong enough that leaning into a curve feels like feeling the g-forces. Take those rides in short sessions; coasters wear people out.

This is closer to an engineering tool than a game: no levels, no missions, no points. That means a real learning curve, steeper than the usual theme park builders, and the editor takes time to understand. It also means the tutorials are worth their weight, and once they click, the depth opens up: scripting, custom scenery imports, a force vector designer, a light pattern tool, weather and a full day-night cycle. The realism is not just for hobbyists. Real coaster manufacturers, including Vekoma, Intamin and The Gravity Group, have used NoLimits for layout, design and marketing, and professional designers have tested physical coasters in it.
