While Syndicate has a fun narrative overall, it's hindered by the fact that Ubisoft worried more Evie would mean fewer sales, when that's not necessarily the case. Each twin could've had a solid, fulfilling narrative if their screen time was truly split 50/50, but as we'll look at next, that's just not the case. Unfortunately, because of the way each twin's time onscreen is split, Evie's character arc is more rushed, and Jacob's is arguably a little too drawn-out. The story of Syndicate does include a character development arc for each twin: Jacob learns to better follow the Assassin's Creed, while Evie learns that the Creed isn't everything - there's more to life.
But Ubisoft, known for having trouble including playable females in past Assassin's Creed games, decided to change plans: instead, Jacob got more quests than his equally capable sister, Evie. Equal amount of missions to embark on, and qqual time for the players to take on the persona of each twin. During development of Assassin's Creed Syndicate, Ubisoft originally planned for both twins to have an equal amount of screen time in the game.
