It was released on PC a year ago, Microsoft Flight Simulator was released on Xbox Series X/S, where it’s also available via Game Pass. It’s a large game, measuring in at nearly 100GB—and that’s not including any of the optional “world updates,” which can make its file size inflate well beyond that. But you needn’t download the whole thing to get it working on a next-gen Xbox.
Microsoft Flight Simulator comes in two files on Xbox Series X/S, one that combines the game (42.4GB), and one that enables you to play in an offline mode (59.7GB). You can play the game without that second file, provided you A) have a solid, stable internet connection and B) don’t have a data cap. When you first get the game, you’ll get the chance to select, piecemeal, which files you want to put on your console. Or, if you downloaded both and need to remove the second one,, follow this…
Since Microsoft Flight Sim is a next-generation game, you have to keep it internally or on the $200 expansion card. If you’re rocking an Xbox Series S, which comes with just 364GB of internal storage capacity, Flight Sim takes up about a third of your disc space. On Xbox Series X, it takes up an eighth. In either case, that’s not much space for other massive games like Destiny 2.
According to Digital Foundry testing, Microsoft Flight Sim uses anywhere from 500MB to 700MB of data per hour, so, if you have a data cap, you might want to limit how much Flight Sim can use. You can set change restrictions in the game’s “Data” tab, under the “General Options” menu.
