Elden Ring is a video game, and it's a very popular one. According to the NPD Group, which tracks monthly game sales, it's the bestselling game of the year so far, selling over 12 million copies in the month it's been available, and it's already in serious contention as one of the best games of the year, if not recent memory.
Elden Ring has been out for almost some months and is considered by a lot of gamers to be the best game ever made. Elden Ring doesn't have to be a singleplayer adventure. It's great as a solo journey, maybe aided along by the occasional helpful summon to get you through a particularly tough boss fight.
