Joe Gatto (from Impractical Jokers) and Henry Cavill (from Superman/the Witcher) are both AC fans, Henry’s favorite being Syndicate and Joe’s favorite being 4.

Every protagonist’s voice actor since 3 are from the places the game takes place in/has the same ethnic background as the protagonist. A good example of the first one would be Kassandra and Alexios, since both of their voice actors are greek, and a good example of the second one would be Connor, since his voice actor is Native American.

AC is the best selling Ubisoft franchise to date.

Assassin’s Creed was Kristen Bell’s (who plays as Lucy) first time voice acting.

AC’s crossover with Final Fantasy was not intended to be the last, and it’s likely that there will be another one once Final Fantasy XVI releases later this year. Not sure what to think about this one personally.

AC Valhalla has random Easter eggs that are easy to find, but hard to notice. My favorites are one with Skyrim, where if you look closely in Winchester you will find a page that references/is similar to the Lusty Argonian Maid, one with Rapunzel, where you’ll find a tower that has a vine going down it obviously referring to her hair, and one with Zelda, where you see a butcher getting beat by chickens in a cave, referring to how in Zelda if you kill/hurt too many chickens a swarm of them will come to you and beat your ass.
