I'm going to pretend I never clicked that link
edit: Team Fortress 2 is one of the defining titles in the team-based FPS genre, but relative newcomers to the genre, most notably Overwatch, outclasses it in gameplay, visuals, and the enjoyment factor. Even Valve's other multiplayer FPS, Counter-Strike: Global Offensive, has remained more relevant, given its recent visual overhaul, transition to a free-to-play structure, and new battle royale game mode. There's no need to start playing TF2 if you never have in the past, and current players should make the jump to newer (and better) titles.
