Wow didn't know there was a open source roller coaster tycoon 2 clone, that would be interesting to mod into some sort of server traffic representation.
It looks like it requires a local copy of the original Roller Coaster Tycoon 2 to work. Why is that?

"OpenRCT2 needs the object files (containing graphics, sounds and models) from the original RollerCoaster Tycoon 2 to work. You'll need to have a copy of RCT2 before beginning."
