Evolving gameplay as well. What I mean is how they all mesh together. The way the new guys handle and feel in game. The way the vehicles handle and differentiate themselves from each other.

New ways of presenting the story. Let us discover. I'd prefer to have all this open space and use it. Don't give me all this space and make me walk the same little line. Just my two cents. There's a framework for epic. Let's go there.
