what makes a rollercoaster good...fear factor, speed , height hoặc gimmics and do bạn have any cool pictures hoặc video

All of the above!

Fear factor and speed!!

bạn don't need height, the last rollercoaster I went on was không gian Mountain 2, and it was in the dark (another awesome factor, bởi the way!) so obviously we couldn't see how high we were.

And I honestly don't think I would enjoy rollercoasters half as much if I wasn't a little bit scared before I got on them. The fear is almost enjoyable! :)
