>>14777148I'll go ahead and second All Flesh Must Be Eaten. To me a lot of RPG books suffer from trying to do too many things at once, cram too many concepts, playstyles, and genres into one setting and system. AFMBE doesn't have that problem. It is laser-focused on zombies. All zombies, all the time. The word "zombie" or some slang thereof appears at least five times on every page. There's a love and dedication for the genre dripping from every page, and it makes no pretense to being anything "grander" or "more sophisticated" than a game about zombies. ZOMBIES.
Plus, the Unisystem it uses is simple, enjoyable, and above all malleable. While you really don't need them (the game works on a point-buy system, so it's easy to houserule anything you'd ever want into the game), there are tons of splat-books for the game for if you want to run kung-fu zombies, space zombies, fantasy zombies, cowboy zombies.
