The only problem with such statistics are, that a) these are Steam games, which do not include all Windows games such as Fortnite, and b) most AAA multiplayer games that are very popular are not playable on Linux. So 90% of games does not equate to 90% of players. Because for most players in example it does not matter the 20% games on Steam with 1 or 2 players at most (just figuratively speaking). This article leans towards Steam statistics and ignores Fortnite, League of Legends, Roblox, Valorant and even on Steam itself GTA Online, PUBG, Call of Duty games (online part), Battlefield games (online part) and so on.
I am a die hard Linux user and gamer since 2008, but I am not someone pretending that 90% of Steam games playable on Linux is as impressive as the the statistics sound. It is important to tell the entire truth, so people switch based on correct and full information and not on a wishful thinking.
