I don't care if there's only three or four people in the world that care - I'm going to keep bumping this topic. GamesMaster! http://www.youtube.com/watch?v=HlPlgDabFUc (4:25-ish) Sega Park Harlow apparently opened on a Friday. This episode of GamesMaster aired on the 17th December 1997, which was a Wednesday, which means... the opening date was the 12th. Also it was apparently the 13th Sega Park - can't quite be bothered to check the maths on that one.
