hedwards: Trying to define sports is rather tricky, some of them are competitive and some of them aren't. For the most part, rock climbers aren't very competitive, but then there are some that are. Hiking is likewise generally considered a sport, but it's not generally a competitive sport.
Which is kind of what the quote says - there is no de jure definition of what "sport" is, but SportAccord, being a "de facto representative of international sport", has set those criteria as their definition, so that is likely the most commonly agreed-upon definition.
sharp299: Technically is sport, chess is officially considered one. in my opinion I see no difference between Chess and Heroes 3.
Chess may be old but it is still a game
hedwards: By whom though? Chess has basically nothing in common with any other sport other than the fact that it takes a great deal of time and effort to get good at. It's a game, a hobby or possibly a life choice, but definitely not a sport as generally defined.
SportAccord?
(To be clear, I don't really give a damn about whether or not any given activity is included in an organisation's or person's own definition of "sport", or even whether there is an "official" definition for the word - I personally engage in games (physical, mental, and electronic) because I enjoy them. That a relatively few people get famous for dedicating a substantial pat of their life to said activity and/or are paid various amounts of money for winning competitions or whatever matters none to me. I do enjoy taking part in the discussion nonetheless.)
