I mean, people did say that it all looked kinda theme park-y when the Twilight pack dropped. Haha. And there's been shades of it all throughout Planet Zoo's development but I think for sure these two packs are maybe the best examples. That and the Tropical pack clutter... It's more shocking to me that people didn't think of it for the gift shops!I can't believe we didn't think of this with the twilight pack We complained and complained about it being too planet coaster like but no one thought, what if we are a testbed for a coaster sequel. The lava rocks though do work for realistic builds, everyone needs to build a galapagos area to see they do work in a zoo.
"Testbed" might be too strong a way to put it. But if they can find ways to be efficient and get a sense of how people might react to features in a new game... Why not?
Hotels, elevators, new food options and even things more QoL-related to the controls or lighting or whatever might signal something for the sequel.
As for the lava rocks? They have their uses! But they'd be infinitely more useful for a theme park, I think.
