But, if he never plans to work on the game again, what is the point of hording those assets?Not every developer wants to just "give up" their assets they created and (took multiple days/weeks/months/years to make) and story they wrote for free for someone else to profit off of.
If their assets were bought like a lot are nowadays (reason you see so many of the same characters in every game) that would be different, then someone else could just go "buy" those same assets and take parts of the story and finish it.
It's just a waste.
