Competitive StarCraft tournaments in Korea.

In all sincerity, I do think pro-gamers should be considered athletes when certain games come into question. StarCraft for it's real time strategy multiplayer requires both a deep strategic mind, and the attention span to keep plotting over hours of gameplay. When physique comes into question, the DDR games you mentioned definitely applied.

Also, Speed Runs are amazing. The amount of skill and dexterity that goes into pulling them off are mind blowing, and if anything exceed the rates of an Olympic athlete.
