We're getting a huge wave of nostalgia looking at that image! 1 Vs. 100 truly was a memorable part of the Xbox 360 era, serving as a live gameshow where Xbox fans could compete and try to win prizes while answering quiz questions.
It was a really cool way to bring the Xbox community together, and Xbox boss Phil Spencer clearly agreed, even mentioning in a 2020 interview that he regretted "that we didn't keep it going". Unfortunately though, it's never returned.
That's seemingly not for a lack of trying. Spencer mentioned that he and his team were "on the case" a few years ago, and reports suggested that something was "definitely" being worked on... but nothing ultimately came to fruition.
