Perhaps? I never got into the games - I played the first for maybe an hour or so and got bored, otherwise I've seen other people play other games (mainly the fourth one with the pirates). The concept is an alright one, but it is easy to question whether or not they should have included the Animus concept into the film's narrative in the first place. I still have trouble thinking whether or not it actually benefits the story in any way.
The Animus barely benefits the GAME.

I say this because Im only on the 3rd rendition of the game (A2), although I bought most of them. I keep getting stalled in the game, because - you guessed it - I get bored with it. The first was very repetitive, and I thought - "how many stalls can I knock over in how many cities??" I quit that game for over 2 years, and finally finished it when the 2nd one came out for a completionist reason and I was bored - also didnt want to start the 2nd w/o finishing the first.
Here's the thing: the games do get better/more interesting after the 1st one, but I do end up taking months/years off (from boredom) from them. I actually think DESMONDS story is more interesting than the Animus story - we never get actual movement on that tho. Its like they cant figure out which story is the actual draw, so they throw a lot of stories at you.
It works for offhand fun, and the game has unparalleled beauty of scenery. I mean - the stunning visual beauty of the game itself is probably 70% of the draw for me. I feel like they fail in trying to make the game SO epic and global in storyline, that you lose the strands, and the attention of the audience.
Its so back and forth I have NO IDEA how they can translate that into a cogent movie.
In terms of the game? Assassin's Creed became the avante garde of stealth FPS. I love/hate it because they literally remodeled
Thief to mirror AC, down to the longer hoodie. I liked Thiefs crouching frame and hoodie.

I loved the Thief series, and changing it to more closely resemble AC cheapened it imo.
Dishonored = AC in a steampunk era, complete with climbing structures and backwards jumps (with a slight nod to Thief).
Given that kind of effect - how could they NOT pay homage to AC with a movie?
