And World of Warcraft, and Overwatch, and Diablo, and Crash Bandicoot, and Spyro, and Hearthstone, and Starcraft, and Heroes of the Storm, and Tony Hawk, and Guitar Hero if they decide to revive it, and other smaller franchises that could be revived, plus an absolutely massive back catalog of games that could be added to Game Pass. Honestly it's probably underpaying for what you're going to get out of them.
EDIT: Which btw it's kind of absurd what Microsoft owns now, 5 years ago if you would've told me that Elder Scrolls, Fallout, DOOM, Call of Duty, World of Warcraft, Candy Crush, Crash Bandicoot, etc. would all be Xbox 1st party franchises I wouldn't've believed you
