I just had a look at the video for the game, and I have changed my opinion slightly, the canon ships that are in the game do look good, I still think they have a slight injection of the supposed new Enterprise to them.
The Borg ships look good, the Galaxy Class Bridge looks accurate along with the Uniforms and Character Models.
There were somethings I noticed that looked blatantly wrong, but from what it looks like, they could be fixed with retextures.
I'm not sure how customizable the Game will be due to it being an online experience, I'm thinking it could prove difficult to modify it extensively, then again I have not really got any experience with Online Multiplayer games of this type.
