There’s no way Musk “works” 100 hours a week. How do you think he’s found all this time to spend with his new bestie Donald? By all accounts the guy spends a significant amount of his time playing video games and on Twitter. His “work” is lunch meetings and zoom calls with the board where he just spitballs a bunch of nonsense.
One RPG that does a really great job of circumventing this is Morrowind. Early in the story there are several natural breaks where the PC is encouraged to do side quests and immurse themselves in the world. Once the main quest gets going it starts to take precedence, but the world ending threat builds slowly at first.
