Even at secondary school, Jan Paul van Waveren spent more time on computer games than on his homework,though he doesnt seem to have suffered from it. At university he spent some of his time linking up personal computers with his friends, trying to blast each other to virtual smithereens in a game of Doom. Van Waveren is now on the verge of being awarded his Master of Science degree for a thesis on the artificial intelligence he developed for the Quake III Arena game. He has already started working for the American game company, id Software.
