02/05/14: "Sonic Heroes", next to Totteridge & Whetstone tube station
Just down the hill from the tube exit is a block of flats with a small front garden, where I found this Nintendo disc. According to Wikipedia, "Sonic Heroes" is a videogame whose story "follows the journeys of four individual teams of three on their search for the mad scientist Doctor Eggman. However, Sonic the Hedgehog's clone and nemesis, Metal Sonic, is secretly manipulating the game's events in a plan to eradicate his long time foe." Unlikely to play.
