Game engines used by Steam games

Which engines Steam games are built with, the most reviewed games of each engine, and how many games run on Mac, Linux and Steam Deck.

Engine data comes from Wikidata and covers 9,351 games of the catalog, mostly well-known titles, so the counts show the engines of notable games rather than of all of Steam.
