Just a thought:
A Star Hero campaign that combines Star Hero with Fantasy Hero.
Race - Same A Fantasy Hero, races would have their own planet(s)
Magic - Magic would run on Mana, some planets and parts of space have it some don't
Weapons - Technology based but Fantasy Based as well. Lazer Swords & Axes. Crossbows & Bows that fire lazer bolts and so on
Ships - Star travel but he race would have their own version of starships with some common ships as well. Thought about using ships from various other games, such as Traveller as well.
Creatures - Fantasy based creatures to encounter and new "space" type as well.
Just a idea I'm kicking around
