I had a good year with my Series X. Would give it a 7.5/10.
Sure, there weren't a lot of significant new releases compared to previous years but that's not an issue specific to Xbox.
Gave me time to play some fantastic older games such as:
Kingdom Come Deliverance, Steep, FFXV, Control: Ultimate Edition, Shadow Tactics, Desperados 3, Deus Ex Mankind Divided, Nier Automata, Star Wars Jedi Fallen Order, Hitman 2, Valkyria Chronicles 4, CoD: MW, Shadow Warrior 2, Mafia Definitive Edition, Diablo 3, Yakuza 6, Marvel's Avengers, Asura's Wrath, Ace Combat 7, The Division 2,
Played also quite a few new releases thanks to GamePass.
Still have to get Watch Dogs Legion, AC Valhalla, Immortals Fenyx Rising, Marvel's Guardian of the Galaxy, Tales of Arise, Nier Replicant, Resident Evil Village, Life is Strange True Colors, Far Cry 6.
