[Suicide Junkie]

How about a space combat mod? (Applies to trek, wars, b5, etc)

Firstly, your health represents "hull integrity".
You mana represents the amount of power available from your reactors and batteries.
The spells form most of your technology, using up power to operate.
You would have protection spells act as shields, speed spells to represent engines, and various offensive spells to form all manner of turbolasers, phasers and etc.
Bows could be turned into torpedo launchers and other limited-ammo weapons.
Fighters could be launched via summoning, but they wouldn't really be able to be recalled.

Armor could be the class of ship you're in, and give appropriate modifiers to your hull strength, speen, regen rates and more. Like a pirate, if you find a better ship, you get to take over and sell the old one for scrap. Having no armor would be the equivalent of an escape pod, say.

Helmets, buckles, boots, rings, and gloves could all be turned into custom equipment packages, including long range sensors and repair droids.
Naturally, the world map would be dark, and the sensors would be enchanted +light objects.

Swap the grass with starmaps, the mountains with asteroid belts, the swamps with nebulae, and so on. The worldmap could represent the galaxy, quadrant, or hyperspace, while the first level of dungeons are the individual starsystems, complete with planets and asteroid belts and hostile aliens.

A second level of dungeon would allow you to zoom into a single planet to gather treasure and talk to the natives.
