i don't know if such list exists, but if it does it would be a massive list cos pretty much any well-known PVP game (and even some obscure ones)and multiplayer has some sort of competitive scene. Liquipedia, a wiki for esports, does have a list of a bunch of esports but they're still missing a LOT of games
So it was an interesting thing to exist. Something to think about.
(and even some obscure ones)
What do you mean by that? I got curious. What kind of games are we talking about?
