We don't want your ordinary game trailer - we want a movie trailer with pacing, camerawork, lighting, blocking and all that stuff. This means 11 shots, each one containing about 50 completely new assets, environment art, TONS of frame animation, engine-generated light, maps, textures, and what not. Who could have thought this would take more than 2 months? The answer is - everybody and nobody. Ahhh, gamedev, you got us again, what a prankster.
All in all, it's fine. We'll keep working our asses off and telling you all about it.
