Online competitive gaming is increasingly mirroring the world of professional sports. E-sports are attracting hard-working teams that compete for millions of dollars in prize money.

"A lot of it comes down to reflexes, but a lot of [it] is strategy," says David Gorman, a sportscaster for the popular e-sport, Dota 2. "It's very much like chess, except it's in real time. Almost like speed chess."
