I remember perfectly the day I discovered Spy Hunter in the corner of the Hawes Inn. Video games were still in their infancy back then and Spy Hunter looked quite advanced for its time (to me). I was fascinated by the long road with its top-down perspective. Where did it go? How long did it go on for? I was terrible at the game (and I fared little better at the Commodore 64 version later on), but that didn't mean I didn't enjoy playing it. From a 2013 viewpoint it has dated a bit, though it still holds up as nothing more than an enjoyable way to spend 10 minutes. I'm not too keen on the gear shifting though as 2nd gear almost certainly leads to instant death.
There was talk of a movie version of the game a while back, directed by John Woo and starring The Rock. Exactly WHAT this would be about is beyond me as the premise of the game (drive and shoot) is about as thin as it gets. The game couldn't even be bothered to make up its own theme tune and instead uses the Peter Gunn theme by Henry Mancini.
Probably one the top 10 classic arcade games.
