I've only tried one of the two by Florean then, that's cool to know I've still yet to discover something!
However, there is so much potential and I truly believe we should be seeing a lot more opportunities. They're pretty low maintenance after the construction/design phase, and an implementation within attraction queues would be so cool too.
Also, we need to get on the coding side of things and develop our own fun spells and whatnot. Any coding gamers out there?
