While there are no prizes during Extended Play, a player's participation contributes to the chance that they will be selected to join The Mob, or be The One during the next Live episode.

Players are able to submit questions to be considered for inclusion in the Extended Play mode of the game via a web interface.

The game was due to be released in November 2008 with the "New Xbox Experience" update but it was delayed (as was the rest of the planned Primetime content).

[29] Microsoft's AltspaceVR team has been rumored that they were working on a 1 vs. 100 as of November 2021, based on the same technology developed for online meeting applications, with support from Xbox Game Studios.
