I'm going to say that was a lousy trailer, and the VA, even if they had decent equpment (which might be questionable in some regards), was of a quality below that of many FSO campaigns I've played - all or most of which were not done by professionals. (And note that a great many of those campaigns were actually very well acted... this wasn't...)
On a secondary note, the ability to produce a stand-alone game is beyond most of us, so I'm going to cease my judgment of their product here. However, if trailers alone sold a game, this would never get my money.
