Sir Peter Molyneux?
KBV writes "It seems that for the first time in history a games developer has been granted an OBE (Order Of the British Empire) by the Queen of England. When Peter Molyneux - the creator of Black & White, Fable, Populous and many other games - was asked by BBC News about the honor he simply said "It's come completely out of the blue, I never would have guessed that I'd have that kind of honour." For the games industry as a whole, this is very much a good thing. It's great that developers are being recognized for their hard work and cultural impact on the world."
... but the award is actually decided firstly by a 'relevent' government committee, and the prime minister comes in later on. At no point does the Queen decide who receives the awards - she simply hands them over.
It's Peter Molyneux OBE, rather than Sir Peter. He wasn't awarded a knighthood. Well done him though.
And it might be worth mentioning that Her Majesty is Queen of an awful lot of other places as well as England.
Jez San of the late Argonaut Software received the title in 2002. Good research!
