Admittedly, I should probably be considered somewhat biased since I have been playing Mutant since the late eighties. Mutant is one of the oldest Swedish pen & paper rpgs, having had a revival through recent remakes of the classic Mutant 2 "Efter Ragnarök" setting; the "Year Zero"/"År Noll" setting is the second release in this revived series and also the first to reach computers. The original Mutant was more or less a Swedish take on Gamma World, while the later Mutant 2, Mutant 2089, Mutant: Rymd and Mutant Chronicles went further and further away from those origins. "Year Zero" is a triumphant return to the Mutant roots, with all the quirks and almost pastiche sci-fi elements of the eighties. As someone who also lives in the real life area where the games takes place, it's good fun exploring both a landscape and a setting I am very familiar with. Highly recommended for Gamma World or GURPS fans, or just for a post-apocalyptic srpg romp in an old-school setting.
