I will most likely do something space related, things like exploration, battles or some crazy mission like fighting a virus or alien in an gigantic solar pannel array control station.
Imagine an large structure falling into the Sun and a group of people trying to prevent or just to escape.
Hmmm, it depends how much control we get over animations, because I have some awesome ideas for different Sci-Fi action animations. If, however there isn't much in the way of animation control, then I would try to replicate the earlier seasons of Red vs Blue (because I am a massive fan of those).
On the other hand, those would require me to work a lot on animations, models and textures in addition to the camera work, so maybe I will just make a chain of cinematic shots of the world.
