The Xbox One is a game console manufactured by Microsoft and the successor to the Xbox 360. It debuted during the 2013 holiday season alongside its main competitor, Sony's PlayStation 4.
Since its release, it has been moderately successful among gamers. Early reviews criticized the console for its "always online" policy and mandatory Kinect device; these features were removed later on.
At E3 2017, Microsoft announced the Xbox One X, a variation of the Xbox One intended to promote "true 4K gaming" and as a motion towards the end of specific console generations -- all Xbox games players already have can be ported to the new console.
