I noticed in the trailer (at 0:29) that the large ship looked very familiar.
This is a 3d model from here: http://www.turbosquid.com/3d-models/scifi-frigate-3d-max/718387
I have played space engineers a lot and I think it would be amazing if I could import my S.E. creations into this game (I obviously need to convert my ships into 3d model files first though).
