5. Guilty Gear X2 (PlayStation 2, 2003)
No series - outside of Guitar Hero - packs more rawk than Guilty Gear. The creators even went so far as to add a guitar-shredding witch, I-No, to the series with this installment. She's named for world-famous producer Brian Eno, who worked with U2 and David Bowie - one of the series' many allusions to music.
If a game's that obsessed with rock, it better roll, right? This intro proves that Guilty Gear can do just that. With a mix of animation and wailing guitar, you'll be primed to fight in moments. Heaven or hell? Let's rock!
