Doubtful. Movie adaptations never live up to the games. Many reasons for that.
Beyond that, if you're talking about any game, I would also beg to differ. AC II was a work of art.
Not likely. Movies based on videogames have never had a good track record cause neither the director's nor the producers ever stay true to the source material.
Nah the first one should be mostly story so it can establish the world and how it works for non gamers that are unfamiliar with it.
If it does well I think the second one will do just that. It definitely has promise. Good casting and all. Also we're at the point where games make more money then movies right?
