okay bitches here is one for the video game side
First off VOL read all the definitions not just one.

a : a source of diversion : RECREATION b : sexual play c (1) : physical activity engaged in for pleasure (2) : a particular activity (as an athletic game) so engaged in
A source of diversion or reacreation would clearly discribe Halo as a sport. So it more than fits the defintion my friend, you might as well call it an example.
Next you say that because it simply isnt broadcasted on ESPN that it isnt a sport. Well lets get away from the tunnel vision and look at it from this perspective.
In South Korea, how much of a sport would
American Football be? Not much of one, if at all, cause no one would compete in it. In fact the level of participation there would make it more like a hobby or a game, not a sport there. But if you want to stick soley with the definition then yes it would be one.
Next look at it from the view of good ole south Korea pertianing to video games. Video Games as a sport are probably just as big, if not bigger than sports like soccer. They have high school video game teams that compete in starcraft, have tv stations dedicated to broadcasting competitions involving video games like starcraft.
So what exactly does all this shit prove, well my friend it boils down to this. In one perspective South Korea, video games are a sport, football (american) are not. In America football is a sport a big one, while video games are much less popular, yet borderline of being considered a sport.
Who's perspective is right? Good damn question, however what you can take from it though, is that Halo can be considered a sport, just as easily as established sports arent by some. Its a manner of perspective, and therefore Halo is a sport.
