.. gee, I don't know but maybe they are substantially different because, when you actually participate in a real-life fighting sport, you are actually getting punched in the face, and it is your actual blood dripping from your nose, and the longer the fight goes on, the more you are gasping for air to breath? ...
Not what I was getting at; it's not about being in an actual fight being more "real" any more than taking a photo of a sunset makes you a better artist than someone who paints it. The point was that popular professional sports, boxing, football, baseball, hockey, whatever, are essentially people making a living playing a game. Kids around the world play these things to pass the time, and the small percentage of people who are the best at these games, are paid to play them against each other so others can watch. The stakes are higher and the game is taken much more seriously, players generally revolve their lives around it, but the basic concept of what they're doing is still the same.
Playing basketball is not what you would call "productive", and the skill of the players doesn't change that. Jersey-sweat isn't feeding the poor or curing disease. I'm not criticizing it for this fact, that's simply what it is, as well as other sports, a leisure pasttime that people built their own culture around. That's the point I'm making; just because an activity is
physically demanding doesn't make it somehow "better", or more respectable, or more important, than any other leisure activity that is technically pointless beyond playing a game. That's why I said that as far as I'm concerned, aside from the literal skills involved, I see no meaningful difference between "skilled players competing against each other with a ball" and "skilled players competing against each other with a controller" that makes one undeserving of being taken as seriously, if you're inclined to take either seriously.
