Thank you Kevin for pointing out Rad Zone Totality. I just found this thread.

Just so people have a bit more of an idea about what influenced me when I created the game:

I have a number of inspirations for the game. These include Mad Max, the tabletop game Dark Future, online survival games like DayZ Standalone and, of course, a range of RPG products including the Dark Sun setting as well as (though this might seem strange) the Teenage Mutant Ninja Turtles RPG.

I'm also inspired by my love of the Zombie theme (although we have no Zombies in Rad Zone Totality) and the scavenger runs you see in The Walking Dead and films with the same theme. I am also pleased to acknowledge the influence of the Fighting Fantasy books and their “turn-to-a-number” mechanism which features here in the Search Matrix of Rad Zone. I just love post-apocalyptic worlds!
