So Mad Max is a classic film series, which got a well-regarded and freakin' awesome revitalization with 2015's Mad Max: Fury Road. Later in that year, Avalanche Studios released the video game Mad Max, which got a lot of influence from Fury Road, but told its own story, a possible prequel to the 2015 movie.
In the game, Max is wandering the wasteland when he runs across the War Boys of the brutal tyrannical warlord Scrotus. They steal his Interceptor and leave him for dead. Max links up with a deformed hunchback "blackfinger" (mechanic) named Chumbucket, who believes Max was sent to him by "the Angel Combustion" to help him complete his Magnum Opus, a customizable vehicle. Along the way, Max helps various survivor camps collect resources, dismantles Scrotus' hold over the wasteland, and despite his best efforts, starts to re-connect with humanity.
I played the game and actually really liked it. It didn't try to re-tell any stories from the franchise, and only used concepts from Fury Road to give it a vague relevance to that year's movie. (Scrotus is allegedly Immortan Joe's third son, but is unfit to rule the whole empire because of his rampant brutality.) Collectibles and other locations that you could explore built on the post-apocalyptic world of Mad Max, giving you a sense of just how fucked up the world was before the end came, and how much worse things got afterward.
But there are some things I would introduce if I could have made the game. More below the break.
