It's likely that there'll be another semi-sequel set in the Assassin's Creed 3 timeline, but what about the future? The next generation of consoles is almost upon us, and the next proper Assassin's Creed sequel will have shiny new hardware to show off. But what do we want from it?
We've had enough of scripted missions. We don't mind a few to push the story forward, but the main assasinations should be deeper and more imaginative. There should be multiple ways to take out your target, big levels with numerous entry/escape points and some element of creative freedom. Think Dishonored or Hitman. In those games you're given a target and the rest is up to you and your imagination. That kind of gameplay would suit the series perfectly.
