Geoff Robinson does not fit the stereotype of a hardcore geek gamer. The 22-year-old student is sociable, an avid weightlifter, studies English and history -- not computer science -- and wants to be a teacher.

But Robinson is also the best American at a computer strategy game called StarCraft: Brood War and he is one of about 700 gamers from 74 countries competing at the World Cyber Games (WCG) 2007 Grand Final in Seattle, USA.
