You've played this game, and you've realised you can't stand it. The levels are badly designed, the mechanics are piss-poor, the voice-acting is Narm-worthy, the controls are downright diabolical, and the graphics look as if they've been shat out the arse end of the last generation after a quick mix of Bran Flakes.
However, you can't help but hum that rather gorgeous title tune whenever you're out.
So yeah. Which computer/video game(s) - from any era, any format, any genre - provided an audial treat to you while serving eye bleach everywhere else?
