We do see some modularity anyway, take the Nebula.

However, I do havea lot of ideas for modular ships, but most FAIL due to bulkhead issues, docking issues, size issues and a few other issues, but I will gladly re-try to make my modular starbases and modular ships when I get a 3d artist helping me

I have one major complaint about the TOS BSG - Laser Torpedoes, how the frak do they work?

The Gal - 1980 before my time, never seen it.

nBSG, now thats worth it, understandable tech, and it lets my "lets build a Defiant" ideas out (small ship, large guns)
