So, I don't know if you guys have ever heard of the BAFTA's but it's the British Academy of Film and Television Arts ceremony. I believe they do it each year, but after a month of the real televised ceremony, they do the game awards which is sponsored by Game.co.uk, this isn't screened on live television, but over the Internet of the BAFTA's website.
Left 4 Dead 2 won the award in the Multiplayer Section.
Here's the website for the other nominations and winners.
