If you want to create the best rollercoaster simulator ever, you really need to feel the hangtime from being upside down and shifting of g-forces when going vertical up or down.
Those flight simulators can probably fly upside down. The electronics probably act the same. But you'll never feel the experience of being upside down because those enormous simulators can't do that.
Also if you're going to ride a rollercoaster inside a NASA Simulator it's probably like any other simulator. Just some shifting forward, backwards and sideways...
My vision of the ultimate simulator simulates all movements 100% accurate. So if I'm going through a corkscrew. The whole machine has to roll in such way that I have to feel the corkscrews forces and the B&M whip at the top of the corkscrew at the lateral acceleration forces.
If I'll ever build my own simulator at home. I'll probably create something like a motorized gyroscope. To recreate all experiences like going through loops, rolls etc. But that will be a hell of work and coding to get it working properly...
