If I recall correctly, this is the first month Superdata is reporting that Valorant's revenue had exceeded that of both CS:GO and PC Fortnite. Valorant is currently the #6 highest grossing PC game, with CS:GO at #7 and Fortnite at #10 (though the latter is far more popular on consoles).

I think this is really significant as CS:GO is game with the most concurrent players on steam with the daily peak CCU of around 1.1m. Of course, we don't know if Valorant generates more or less revenue per player, but nevertheless reaching this of number less than one year after full release is certainly impressive.
