* Star Trek: Bridge Commander aka BCFiles is back! Now on Gamefront! https://www.gamefront.com/games/bridge-commander
I'd imagine it would still be NX. The NX/NCC rule didn't apply in ENT, it was a matter of ship-class designation. The NX-01 and its sisters are all of the NX class.
Here is a scale of the BOP against my JJprise. The jjprise is canon (large scale) and I have made the BOP TOS canon size.So yes it does look small compared to the Enterprise but prime verse ships should not be so different.
There is to much surface detail to have a flat look of the TOS connie.
Much better.
I think the textures need to be slightly darker as well as a more metalic appearance in order for it to have an authentic NX-01 feel.
