It's not Atari, it's Arushi.
Anyways, Most of the time, it's impractical to get real measurements of ride rails unless you had access to such ideas, Like the Nolimits 2 Development team, they have so much support from Gravity Group, Vekoma, and others that have their ability to use the program not only from a marketing program, but for a fun program as well.
While we want realism for Planet coaster, I don't expect 100% realism, We thought RCT3 was the most realistic Theme Park Game to date, and honestly? IT STILL IS!
March 22nd is when Planet Coaster becomes the most realistic Theme Park Game, since it's not technically public yet. RCT3 is still going to be the most realistic for one more week.
