Whilst it was a fun game back in the day, I think a little more depth could have been added without sacrificing enjoyment.

Weapons need a redesign so they have a better defined and clearer role (and get rid of the fragging firepower chart!). Likewise, the ships really need to be revisited and probably redesigned.

Really, I think that GW need to get a copy of David Weber's "House of Steel", and study the notes on designing a Navy in the back of the book (not much point in studying the rest, based on that universe having developing and evolving tech vs. 40Ks stagnant tech!). Too many Gothic ships seem to be solutions looking for problems.
