I don't think it kills AC2 before it even begins. As Doctor_Rock stated, it's fun to speculate. It would kill the game if we were convinced that everything we have discussed in this thread will absolutely 100% appear in AC2 and then have it not appear anywhere. That would be a huge disappointment obviously. But that's also not the case.
Keep the interesting discussion going guys!
i agree… we should keep talkin about how amazin this game is gona be!
