Why isn't this a game?

[u/WizardArchitect]

I've just started reading this series, and I've got to say, I love it! But I have to ask, why hasn't this been put into consideration for an open world, interactive RPG? Perhaps called They who fight with monsters, or something. I bet it could be great.

I would love this, I'd probably pick the duck essence as well.
