One of this year's biggest surprises has been Marvel's Guardians of the Galaxy. Its story is one of the best comic book narratives told in gaming, its characters are grounded and well-written despite many of their otherworldly natures, and its licensed soundtrack is one of gaming's best of all time. While many of those elements work well enough on their own, it seems like the general consensus surrounding the title is that its soundtrack, full of licensed music from the 70s and 80s, is one of the major elements that ties everything together.
