I made some of the tallest, fastest, and craziest Coasters ever built (in the real world). Steel, Wood, Looping, Shuttle, Drop, and even a water slide. I only have the basic RCT3 so don't criticize that its not real enough the coasters once i get "RCT3 Platinum" (WET and WILD) it will be better.

Gwazi Yellow 0:28 Blue 2:01 its the longest Racing Coaster
The Beast 3:45 Longest and 2nd Tallest wood Coaster with the most Track Under Ground
Son of The Beast 4:59 Tallest and Fastest Wood coaster with the worlds 1st wooden loop

See part two    • World Record Roller Coasters in Rolle...   for Steel Coasters and a Water Slide.
