I'm hoping that the Collider keeps it's temporary lead. Kid me loved the Sizzler (AKA, Srambler for kid me) but we dearly need more clearly sci-fi rides to go with the generic and fantasy/aquatic scenery rides.
Whatever ride wins though, I hope the customer pathing gets a good QA pass.
Some of the flat rides flow pretty well, like the Teacups. Others rides like the Rocktopus, can fail to fill seats after Max load+150 second max time because customers would rather circle the entire ride to next to the control booth, rather than walk past the control booth.
