- Basically it's classic fantasy, but with anthropomorphic animals. Which in theory makes it for kids, though the death toll in those books is sometimes closer to something like Game of Thrones :D An open world RPG in that setting could be something completely out of this world. But I'd settle even for a nice 2D point & click. Firefly
- I imagine it as a sort of Space Uncharted, but I guess something more like Desperados could work great too. I Hate Fairlyand
- it's a comic book series about a girl who travelled to a cutesy, cartoonish magical land... and then got stuck there, never growing up, for decades, because she's basically the worst fantasy story protagonist ever. And now she's pissed, hates everything, and is basically willing to find the exit over everyone's dead bodies. I'm not sure how I imagine the game... a comedic American McGee's Alice? A point & click? I don't know, but the series is over, but I'd love to see more of it, in any format.
Firefly seems like it work well for a video game, running missions and managing resources, like Xcom except more survivalish and open world, with managing fuel, repairs, food etc. You decide what missions to run, each with consequences, but you must run missions else you will die.
There is also a game where you run a submarine in a underwater world running missions that might make for a even better comparison, but I can't remember that games name.
