I really want to make a bobsled or spinner that interacts with a building to insane levels. The building engine looks like a much better system than any other coaster program.
If it's open the chairlift has great views, it is on the other side of the lake by the rapids ride.
The disco seems to run a fast program to me (it made me sick while others don't. )
Hmm. I was going to say Ge Force, but there are a ton of other great ones in this thread. The 4d's are pretty damn crazy too.
I also love the first drop on the small intamin ball coasters, like Kirnu
I thing B&Ms are more reliable, but Intamin likes to push the envelope and in doing so get some real winners. Even their foray into spinners (Tornado at Bakken) are awesome.
