This is an interesting point of discussion. For me to consider an event sporting activity, it has to have the characteristic of ensuring and encouraging the physical training/fitness of the player i.e must require a level of physical fitness. Looking at esports and board games, they mostly lack this characteristic, so I don't consider a legit sport.
whats your opinion about horseracing or motorsports?
Horseracing a sport? Yes for me, but motorsports for me is a No.
