Maximum Apocalypse RPG: Core Book

The scavenging and crafting systems are so fleshed out that our group spent an entire session just building a fortified camp out of spare parts. Every rule section flows naturally into the next, making it easy to teach new players without having to flip back and forth constantly.

The vehicle rules are way more detailed than I expected, and my group spent a whole session just tricking out a truck for the wasteland. Character creation actually made me care about my survivor's backstory instead of just rolling stats.

The scavenging and crafting systems are what sold me—there's actual tension in deciding whether to burn fuel searching one more block or head back before dark. Combat runs quick once you've got the vehicle rules down, though I'd suggest bookmarking that chapter.
