5. Introduce A Morality System
Although ever since
GTA let you mow down a prostitute and loot their corpse, everyone's taken to seeing just what they can get away with in any given open-world title, but for AC all that happens is you'll 'Desynchronise' (die) should you kill too many bystanders. The reason? " didn't harm innocents" - something that goes against the idea of watching someone's memories play out, as if everything has already happened and they never did such a thing, how can you control their past to do so? Forget the pain that's now building in your head, as the solution would be to play as someone with far less of a rigid morale compass - essentially what happened in AC: Rogue, the most interesting title in years that got buried under all the Unity hate last year. It wouldn't be too much of a leap considering the elasticated tech on display already. Just surmise there's a newer 'advanced' version of the Animus that actually rewrites (or simulates) history itself Source Code-style, allowing for a morality system to sit underneath a huge number of choices you could then make. From deciding who to align with to which (otherwise-innocent) informants should meet the end of your blade, authoring your own experience in the past events of these games in a way that directly effects the future would be incredible.
