As stated before, the Series X "came" with the hundreds of Xbox games I already had, and could still play. Bought the new COD, even though I don't play that series much anymore, more for zombies with friends. However, between new or old games on the SSD, the load times are awesome.. so nice to play a game within a a few seconds. And quick resume, where applicable.
Will get Cyberpunk soon, as well.
(and as a side note, an added bonus is doing Microsoft/Bing rewards for awhile and saving up points... bought a shock blue controller, a new rechargeable battery pack with USB-C cord, and COD was free as well... all those for no cost. Was nice.)
