I think it's pretty clear that competitive multiplayer games are the gaming zeitgeist (On the PC). Rust, Destiny 2, GTA V + mod, and Football Manager are the only titles in this list that are really played in a non-competitive manner.
Now, its true that in terms of copies sold, competitive multiplayer games are not quite as dominant.
Fortnite isn't really comparable to the list of top Steam games in my replies though.
Like Brawl Stars is also super popular, but it isn't exactly a "competitive multiplayer game" like dota. Most people play it casually without a huge care of W/L.
