Non-player characters, such as the league's owner or commissioner, occasionally delivered dialogue on the website and through Twitter accounts, creating an absurdist horror narrative.

There was a high degree of audience participation, with the game's developers actively engaging with the fan community online.

Blaseball centered on an absurdist simulation of baseball,[4] with fictional teams, featuring random events such as the "incineration" of players by "rogue umpires".

[5] Each player had a name and a star rating, which was used to determine their stats, as well as amusing trivia such as their preferred coffee type and their pre-game rituals.

[10] Narratively, the story of Blaseball unfolded across eras spanning multiple seasons, and was significantly impacted by players' collective choices through elections.

On January 9, 2023, the game resumed with a clean slate, featuring the same teams but with entirely new rosters consisting of both new and returning players.

The Game Band would provide periodic status updates and tease new features during this time before ultimately announcing the decision to end Blaseball on June 2, 2023.

Fans have also contributed by creating art and social media accounts for Blaseball players, leagues, sportscasters and union representatives.
