Microsoft Flight Simulator will reportedly take up almost 100GB on Xbox consoles.
The news came via Twitter user Idle Sloth, who showed that if you select "Manage with Game Pass" on the the game's Xbox Store page, it'll give you the full install size: 97.2GB.
As our pals at Pure Xbox report, that's just the standard edition, too, so depending upon what flavour current-gen Xbox you're running – the X or S – and what edition you'd like to play, it may take up even more than that.
