I refer the honourable gentleman to the publication entitled "High Guard".
Case closed.
Seriously, take a look. There are pages and pages of full page deck plans that show little more than the outline of the ship and little to no interior detail. In what circumstances would that ever be useful ?
As noted, knowing which decks are which systems, or where the engines and bridge are, is good. But on a ship the size of the Sylea, that's all we need.
By comparison, the small craft are great. I know the inside shape and outside. The pictures in high guard (which seem very
Homeworld to me) are very nice.
Essentially, my 'dream rules' for publishing stuff:
1) ALWAYS an external picture. Using the recent S&P ships as an example, the two that stick most in my mind are the Mercenary Carrier and the Armed Junker. Why? Because I know what they look like.
2) For a Regular Starship or small craft sub 2000 dTons - Deck plans, in full, in the format Mongoose has been using, is fine. You get a real feel for the ship and it's not - yet - too big to be able to see what's going on.
3) For a Capital Ship - one or more 'blocked out' views - much like PFVA63 has done for his 2000 dTon warship
Here is fine:
At two or three square milimetres for a stateroom, I'm not gaining anything else beyond a coloured block saying 'this bit is massed staterooms'. By all means provide a deck plan for the 'interesting' bits of the ship (bridge, hangar deck, etc) where action might happen.
4) Ensure that all information is stored in a format that doesn't compress it out of legibility. Vessels in Brian's Warship's of Babylon 5 just about gets away with it for the size of deck plans, but that's because they are entire A4 pages with nothing but a single deck on - and even then, the Narn and Centauri big ships are pushing it. The effort is commendible, but if (like the Victory) the end product isn't readable, what's the point?
