It’s easier to show rather than tell ….
EVE Online is a persistent world, massive multiplayer online (MMO) game, so if you log off it continues to exist for all others playing*. It started in 2003 and as of 2023 has a user base of over 9 million and from experience, there are typically 15,000-30,000 players online playing in one of the 7,800 or so star systems (opening graphic of the first video).
Play via your browser or download the game client. It’s free to play 🙂
