It's because people want to keep the almighty happy. 

'It’s almost May but that doesn’t mean the awards from last year have stopped with Famitsu Magazine holding their 2007 awards earlier this weekend. Nintendo’s own Shigeru Miyamoto has been honoured at the event picking up the award for Most Valuable Person in gaming award. His prize? A bunch of flowers.'

How lovely, flowers.

I bet he was very happy with those...
