Im talking about sports like air gear competitions or like “Keijo”, only thing that matters is that the author has made a sports with rules, be it something completely impossible to play like magic sports or just something that isn’t played in real life but could perfectly be done.
It doesnt have to be the main focus of the story. It can be like what Quidditch is to Harry Potter, just one of many parts. Also, it doesn’t matter how much it takes from real life as long as it is clearly a different thing. (it could be a variation of an existing sport as long as the ruleset is not real)
Having said all that, what are some fictional sports in manga you like?
Yeah D frag also made a board game, but my problem with that is that the results feel random as not all rules are explained nor are the squares shown so you only see stuff happen instead of understanding how it would play.
That aside, yeah fictional sports are kind of a difficult concept to pull off (think of how boring quidditch is) and even when they do most are technically variations, but I’m fine with that, if there is a fantasy magic world where they have real sports but with magic I would still consider it a different thing.
