Hi, I recently purchased all three of the current "Star Hero" genre books, I had held out buying them as "Star Hero" wasn't my favorite genre from the BBB era. While I did like the world, though it reminded me more of "Simon Green's Deathstalker" series, a little. I did enjoy it. Still not happy with the "Magic makes superheroes" idea but it works to a extent and as far as my own campaigns I usually don't dwell on it. But one of my dissapointments came in the form of all these cool sounding ships, and weapons and very little to any pictures to back them up. Not even a layout of how the bigger ships look. So that if my players are fighting through the decks of one of the bigger ships, I have no maps to help them work through it. Maybe it would of been cost prohibitive, or you want GMs towork on that aspect so they decide how most of the ships look or feel on the inside. I don't know. I do know for me personally I would of liked some of the layouts done, as it makes it easier on me for GMing...
I am probably spoiled by my first Champion's GM, who had a thing for Star Trek, and Star Fleet battles, and so in our campaign, we had elaborate layouts of the ships we were on. The campaign was very similair to "Galactic Champoins" idea that you've got coming up.
Anyway since then, I've always liked maps, diagrams and schematic drawings (Much like Battletech), it makes my job soo much easier.. to just pull out a map of the Terran Battle cruiser, when my characters are bording one. Or have a drawing of the Pulse Hand Blaster or Hovercar, they are using.
When you are creating a unique universe, it's all in the details that bring it home.
