I don't know if I have any direct advice or comments to offer to our protagonist, per se, but there is one thing that does come to mind
in the story of Ni No Kuni II where he will
attempt to negotiate with five different kingdoms throughout his adventures and
form a contract, and that can be kind of similar to the gaming industry where I often find myself
in a position of course where there is the company that makes the
game engine, there is the company that has the
video codex we use, and there are so many parties involved and you have to unify all that towards one common goal.
