I feel like i'm missing something, in the way you explain it sounds like "Customise Rides" and "Change Ride Animations" is the same to me...
I think i'm not quite undestanding properly what do you mean with "changing sections" (and yes, i watched the video again, it's 4 times watched now xD)
Haha yeah I get it, its difficult to explain, what they're doing with rides is something that has never been done before. Changing ride animations and speeding up rides etc. I wrote that as modular rides, customize rides is just changing paint colors, surrounding fences etc. which are in other games. Just needed something to differentiate between the two.
If you can think of a better way of describing it in a title let me know.
