It's the first big original game from Rare in quite some time, the first big Xbox One exclusive of the year, and the first of Microsoft's games to launch day and date on Game Pass. Whatever your reason for playing, you'll be doing so at a different time depending on where in the world you reside. Although it has a release date of March 20, this is an online-only game, and servers go online at various times in different regions.
