See, this is where being a credit nazi actually works in my favour.
As I only count racing coasters or "mirrored" coasters as one (if it follows roughly the same track, then it's 1 coaster) then I have no trouble counting a single circuit (half the track) on a Möbius coaster as one "credit". The other half will give you pretty much exactly the same ride, so why bother?
On another note, Möbius coasters absolutely fascinate me, and I once created an entire half a park in RCT3 where everything was Möbius. Möbius rapids, Möbius rocket coasters, Möbius Dive Machines, Möbius log flumes and probably Möbius carousels. I submitted my park and ideas to several theme park owners and ride manufacturers actually and I'm hoping that I'll get the good news in a couple of days that I've been hired as their new chief design engineer - so excited!
