How about one with dogs that lived in the wild and then an apocalypse hit and most of them died? But then a new species was introduced and rivaled the dogs and the dogs have to try to survive without going extinct?
What about one that's dragons, but they run a hotel, and you have to try to get out of it without getting hurt? Because the dragons can turn into scary stuff?
UUUUHHHHHHHHHH whatta 'bout....Some type of horror asylum thingy?
