Key from a Greenmangaming.com giveaway for voting in last year's (I think) golden joystick awards. Good luck!

NB. I don't think this key has an expiry date but I don't know for sure (and I don't think there is any way to check). Please accept that this giveaway is in good faith: I'm putting the game up to give away because I think it is likely to work just fine (I'm 20/20 offered/received so far;-)
