First thing I noticed was 10-Forward. Went and watched a few minutes of Power Play, which took place mostly there, and it certainly does seem smaller in the simulation. The doors also appeared to be in the wrong place.
Also, it looks no different than the parts they had built for one of the Elite Force series games, which also used the Unreal engine. I found most of the games pretty crappy, but there were some very good missions/levels that took place aboard the D, and a largely blown to bits Excelsior class ship.
