THIS LIST IS UPDATED REGULARLY AFTER PROGRESSES!
THE "100% COMPLETION" GAMES ARE LISTED BECAUSE THEY ARE EITHER NOT PLAYED ON THIS PLATFORM, (MOSTLY ON PS4-PS5) OR HAVE NO ACHIEVEMENTS ON STEAM!

Played all games from the Assasin's Creed franchise but when I was younger I did not care about the 100% completion in games, but I'm planning to do them all, like I'm doing it with the new ones!

Assasin's Creed Origins: 100% Completion in 80-90 hours (not sure) (Nightmare difficulty)
Assasin's Creed Odyssey: 100% Completion in 137 hours (Nightmare difficulty) (With all DLC's)
Assasin's Creed Valhalla: 100% Completion in 125 hours (Berserkr difficulty) (Didn't like the stamina mechanic and the lesser assasinating options that came into the game so I lowered the difficulty level from Drengr)
Assasin's Creed Mirage: 100% Completion in 22 hours (Hardest difficulty)
Assasin's Creed: 2019 Worlds 1v1 (Console category) top 33th place (Odyssey and Origin games)
