Mad Max Fury Road. They defeat the tyrant, and get the control of the water valves. Then they open the valves and seemingly keep them open. One problem, how long is the water reservoir gonna last now?
Logan’s Run. The city dwellers are freed from the computer’s iron-fisted rule, and Carrousel. But their city is in ruins, and thinks to the computer providing everything. They don’t know how to live without it. The city dwellers are going to start dying off real fast.
Max is a pseudo-mythological figure. It’s never clear in the movies how much time has passed. Word of writers says that he’s multiple people retold as one person in retrospective story, but the movies don’t show that so you can take or leave it. The game has him as an immortal doomed soul.
Whatever is the case, I think it’s pretty clear we’re not supposed to take the story we’re told about Max via the movies as told completely faithfully.
