Zoo Tycoon used to be my jam along with Roller Coaster Tycoon and Battle for Middle-Earth. I remember making animals for the original games and uploading them onto the Internet where no one would download them.
Having a Nintendo-themed zoo game would be pretty cool.
I've TOTALLY thought of a fanon concept of the greater Nintendo multiverse having a zoo, especially since Subspace Emissary at least had an abandoned one, but at least personally I had some. . . . issues that occurred to me thinking of the concept. I personally just defaulted to a Flamii exhibit and didn't think through much else, but thinking on it now, in general Xenoblade and Pikmin would largely be the safe stuff (with exceptions), with Zelda having some degree of contribution.
From there it starts to get. . .ethically murky.
There a lot of stuff that tends to range from "sentient" to "practically people" to "Crazed starfish amalgamation of the tortured souls of the dead that needs to simultaneously be put out of it's misery and wiped off the face of the planet before it kills someone. And is also kind of sentient."
Then again Zoo Tycoon has the mermaids, so that's already fairly questionable. And there were some exhibits that zoos had in the past in real life that today would be very, very, VERY, VEEEEERRY bad. . .
Did we REALLY need another fire lion pokemon
No.
Then again, we don't need another *insert practically everything the fandom asks for, particularly when it's because the current example did it "wrong"*, either. I'm gonna be a smidge salty if it's a lion, but then I was leaning towards Moon off of the logos anyway.
Hopefully everyone is just jumping to conclusions like we love to do.
*EDIT* And since I already sound far too salty for this, I would like to clarify that I will also likely get over it within a rather short time frame. Point is, if the butterfly/moth clogging is a huge deal, than all repeats are worth making some degree of fuss over. No use playing favorites when the number of fully unique, non-inanimate (inanimate also being seen as an issue by the fandom), non-humanoid (humanoid design also being seen as an issue by the fandom) designs is diminishing by the generation. Granted, the buttermoth situation is a bit worse for all the cool Bug ideas being passed up, as well as the identical frog situation for all the Water-types, but since when is anyone going to bring up type specific issues? It's all about either the concept of repeats itself or the fact that it edges out a vague fantasy concept of what would be cooler, often one of a completely unrelated type.
