Watch_DOGES Legion update:
Stayed up until 1AM last night, enjoying the game.
Despite establishing that Assassins Creed is a game in the WD universe, Legion reverses that, and claims that Templars and Assassins are organizations about which the world's foremost conspiracy-minded AI cannot find any references.

Encountered a set of missions which led to a fun chance to recruit Darcy, an Assassin with WD-themed tools, by getting her into an AC: Syndicate-related tomb.
HOWEVER, once the mission was completed at 1AM, Darcy isn't added to my team. Long story, short: Darcy's missions are part of the Deluxe Edition, but the Season Pass is separately required for recruiting her.
Researching it made me realize that much of the negativity in reviews of this game come from the monetization schemes in place in this full retail game. In WD2, the main game was essentially complete, and there was no compelling reason to get the Season Pass. Ubisoft went ahead and released a bunch of that Season Pass content later, wanting it to be played -- and paying customers complained that their purchase was diminished by the giveaway. With Legion, they have in-game credits for sale, exclusive characters, clothes, etc.
I'm not a fan of unclear messaging in-game: can I recruit her or not?
Trying to picture how I'd feel if GTA V had charged me for a car that was better at winning races. Or for Franklin. Or for Franklin's "driving focus" slow-motion power. Pretty sure I'd hate it.
The season pass is on sale, but I don't want to support the business model.
