The asymmetric view and the way the map is set up make it really look like it’s curved. I like that alot. If you look closely, the sides of the edges are also some mechanical theming that make it look like the rings themselves. There’s a canyon, and some elaborate Forerunner structure also. This is definitely a well made map from a re-creation standpoint. How well is it from an RCT point of view, that’s yet to be seen.
He built a roller coaster in the canyon, that looks cool. He even provided the save files so you can download it and try it yourself. Unfortunately, I haven’t gotten around to installing RCT2 on my computer since the last time I re-formatted, and what with all my Alaska travels, I won’t have time to try them out for awhile since. Someone else can though. It looks cool.
