Tales from the Borderlands. Granted, Borderlands doesn't have the most sophisticated lore, subsisting largely on dick jokes, pop culture references and lots of screaming jerks, but suffice it to say that you don't have to be intimately familiar with Gearbox's first-person shooters to appreciate Tales. If you know that Handsome Jack is a villain, perhaps heard his smarmy voice in a trailer or two, you should be fine.
In other words, regardless of your level of Borderlands experience, Tales from the Borderlands is a witty, well-written adventure with broad appeal. And yeah, there's a dick joke or two.
