New poster here, rather revive this thread than start a new one just on foxes.
The game really should have foxes and maybe lynx. The forests, while beautiful from a graphics point of view, are mostly empty except for a ton of hare, some deer, and occasional boar. The game has no predators.
Wolves, as others have mentioned, probably should not appear in the game in large numbers - or else KCD would be like Skyrim where Henry has to fight off three wolves every mile or so. Same with bears because KCD’s map only represents one county of Bohemia.
But foxes and perhaps lynx would be easier to add from the Dev’s point of view because these animals don’t attack humans (avoiding issues with NPCs), don’t attack large adult herbivores like deer or boar, but do attack small ones like hare (the game really has too many hares).
Also, when were rabbits introduced into Bohemia? Rabbits, not hares.
I think birds, insects, and reptiles would be nice additions to the game, but obviously that’s not a high priority unless the game has a long life cycle and gets a graphics update. Also, considering how bad Henry starts off in archery, bird hunting would not be very productive unless the Devs add a falconry mechanic.
