Star Citizen's new trailer claims all the footage is taken from the in-game engine, no pre-renderings, but it is so amazing, so detailed and beautiful, so impossibly complex, that I just can't believe it. If it is really this way, I will buy a PC, an Oculus Rift, and disappear forever from the face of the Earth. It is incredible.
It's not even the amazing graphics. It's the apparent complexity of this alternate, apparently never-ending universe. I really want to explore it all.
