Geoff Keighley is a gaming journalist who frequently does work for GameTrailers and Spike TV.

You might know him as the host of GameTrailers TV, which has featured Valve announcements and news before.

He also does “The Bonus Round”, a roundtable talkshow also featured on GameTrailers.

Some veteran Half-Lifers might know him as the man behind “The Final Hours of Half-Life 2”, a massive GameSpot feature chronicling the development of Half-Life 2.

He also happens to know a lot about this Saturday’s Spike TV Video Game Awards.

After the ” Give & Get” sales of Thanksgiving, it would appear there’s another phase of holiday sales we need to go through until we get to the motherlode: the Christmas sales.

From the 6th of December to the 20th, Valve will be running the “Great Steam Treasure Hunt” contest-hunt-metagame-thingy.
