The problem with some types of flat ride is that they can be too 'fairgroundish'.
I think that is a huge problem with flat rides. However, if they were themed or were inside, you would see very little of the rides.
I have an idea for a few flat rides that would fit in well with X-sector or around SW6.
If it were in X-sector, it would be another experiment inside the black hole tent, it would be a series of flat rides that all do something you wouldnt expect. It would be themed as if you are test subjects for something.
If it would be around SW6 then it would be a magic area, with the same rides but themed darker and mystical.
The first ride i would have would be a rotor flat ride. [url=http://www.youtube.com/watch?v=J7k8Oz_73mw" onclick="window.open(this.href);return false;]http://www.youtube.com/watch?v=J7k8Oz_73mw[/url]
thats obviously the removal of gravity, can be done as an experiment or by magic.
The second ride would be something that effects another sense, something like the tunnel in Duel that spins and causes you to spin, i once went into a room that had a platform that you walk along while the room spins around you. Its very difficult to walk straight and for some people, to even stay standing.
The third would again be something that does something you wouldnt expect. More then 3 rides/effects and it would take too long to get through.
Also the rotor and spinning room take up very little space and so you could have multiple of each in order to maximise throughput.
I only came up with this idea because i love the rotor ride so much and would love to see one at AT
