This music video by Ithaca Audio celebrates 35 years of video game music by mashing together popular tunes with classic video game themes.

That alone isn't enough to truly make the 'Game Theory' video unique, as there are tons and tons of video game music mashups and themes all over the Internet. However, what if I told you that every one of these tracks was mashed together live using nothing but rewired NES and N64 controllers? The results are impressive as Ithaca Audio mashes classic video game themes from Super Mario Bros, Tetris, GoldenEye, Street Fighter II, Arkanoid, Call of Duty, Grand Theft Auto IV and Final Fantasy VIII with vintage pop themes from ABBA, Michael Jackson, David Bowie, Basement Jaxx and Run DMC. Throw in the familiar hook from the Doctor Who theme, and you've got a video game music mashup for the ages.
