starcraft
One of the greatest RTS (real time strategy) games of all time. It was produced by Blizzard Entertainment in 1998, and has remained popular with over 30 million copies sold. 

In the game 3 races, Zerg, Protoss, and Terran (human) face off in an intergalactic free for all. The game was hailed as on of the greatest with regards to balance between the warring factions. One of the greatest players of all time is Terran, whereas beginning players enjoy Protoss and Zerg. Moderate players can usually play as any of the races and it can be anyones game. 

South Korea loves Starcraft. They have competitions, where as many as 14 kids from each of the 6 major teams compete in front of a stadium of people. The best player in the world can make upwards of 200,000 dollars. The training players are lucky to make 600/month. 

On a personal note, one of the greatest games of all time. Starcraft 2 will be coming out soon, hopefully they managed to do everything Starcraft did, but even better.
