I was thinking of running a starcraft-themed game here, using the Prose Descriptive Qualities (PDQ) system of rules. Here's the intro blurb, with application and character creation rules to follow. Chronologically, this takes place just prior to the start of Starcraft 2.
Far out on the fringes of known Dominion space lies the mostly unexplored world of Leviathan VII. Survey ships have mostly passed this world by until now since it contained little in the way of usable minerals or vespene gas. However, after small numbers of Zerg were confirmed there recently, a more detailed investigation was launched. It was highly unusual to see zerg outside of the Char hive cluster these days, so a people took note. After more careful and detailed scans of the planet, a special energy signature was noticed. It was highly unusual, though not entirely without precedent these days. It seemed to come from some kind of Xel-Naga ruins deep underneath the planet's surface.
With this discovery, Dominion archeological teams with support from the military launched a full-blown investigation of the system. The Leviathan system had a highly irregular sun which intermittently released large blast of radiation, so many figured that the sun was at the end of it's life, and that end was approaching fast. Perhaps unnaturally so, which hastened the investigation. No one wanted to be nearby if the sun blew, after all. Only Leviathan VII was anything like habitable, the other planets were little more than rock. The ruins were interesting enough to warrant a research base on the planet regardless of the zerg thread. From all accounts, the zerg weren't moving that much on the surface. Protoss ships had also been sighted, apparently following the zerg, which was yet another reason to hurry the investigation. Everybody knew what happened to zerg-infested planets when the protoss were nearby.
The investigation was just starting to get properly underway, when something unthinkable happened: Some radiation pulse spread from the sun through the entire system, destroying many of the orbiting ships and forcing the rest to crashland on Leviathan VII. It made no distinction between Terran, Protoss and Zerg either, anything that was moving in the space of Leviathan system was either destroyed or forced to land under bad conditions. No takeoff had been successful from the planet since.
Now, you only have one goal: To survive Leviathan VII and find a way off the planet. You may not have much choice in your allies... If you wish to survive.
Here's the deal: I'm running the game using PDQ rules, which are free and can be downloaded from Atomic Sock Monkey website under freebies, PDQ core rules. Here's a direct download link: http://www.atomicsockmonkey.com/freebies/di/pdq-core.pdf
Rules are very simple, PDF is only 13 pages. Character creation will use the following guidelines:
Name: Self-explanatory, I should hope.
Race: Terran or Protoss, which you take as Good (+2) Quality. More on them below.
Profession: What your character does for a living. Taken as another Good (+2) Quality. Anything you can think of is okay, as long as it fits with the race. This covers everything someone in that profession would be familiar with.
Background: Short description of how your character wound up on Leviathan VII.
Other Qualities: You get 5 Good Quality ranks in addition to the 2 free ones above. You can take them in whatever combination your desire, all separate or stacked to get better ranks. You can stack them on race or profession Qualities as well, to get them to higher starting ranks. You take one weakness at the rank of -2 Poor, like in the example.
What your character generally has with him/her. In case of weapons, if the weapon is highly specialized or unusually high quality (common rifle/pistol is not) it gets an upshift for damage rolls.
In the case of some professions of Terrans and for all protoss, they may have access to armor. All protoss are equipped with Plasma Shields, and some Terran military personnel are trained in the use of Powered CMC combat armor. When wearing armor, all enemy damage is downshifted one rank.
Equipment bonuses, whether on weapon or armor, have no effect on hit chance, only when damage is calculated.
A few notes on specific Qualities:
The protoss are an innately psionic race with a highly regimented caste system, which means that the only knowledge that all protoss share is related to their history and culture. They can generally use all protoss-made technology, but have no universal combat training, thus cannot add this Quality to combat checks unless they are psionic in nature. However, protoss can add this quality to all psionic-related checks and their total psionic level is calculated by adding race Quality to their Profession Quality, if profession is psionically focused. This often gives protoss higher psi-indexes than humans.
The humans, or Terrans as they are usually called, are a versatile and adaptable lot. They can often find ingenious solution on various problems, and are generally adept with all Terran technology. They are also universally fairly hardy, and even the most bookish librarian can clout someone in the head with a book when properly motivated. Terran can add this Quality to all combat checks.
Only Terrans can take this quality, as all protoss are innately psionic. This Quality represents above-average Psi-index in the user. For Terran Ghosts, this is a mandatory Quality. Characters with this quality can use psionic abilities to gather information or affect other minds, or resist other psionic attempts. If Psionic Quality is Expert or better, the Character is also Telekinetic, with the ability to affect the physical environment with their abilities.
Your character, Terran or Protoss, has had an unfortunate encounter with the Swarm sometime in the past. The zerg in one way or another left their mark in you, and you carry their genetic taint with you. You are generally leaner, meaner, faster and just more aggressive. You can add this Quality to all combat checks. However, your appearance and disposition makes others of non-zerg disposition to view you with suspicion and disgust. You take a downshift equal to your rank in this Quality to all social checks involving non-zerg. The higher the rank of this Quality, the father the zerg infestation has progressed in you, both in physical changes and in mental shift. At Master (+6) you are more than half zerg, and have trouble holding to a non-zerg thinking process, often prioritizing your more brutal urges and trying to link up with the zerg collective.
Sample character: Protoss Zealot
Race: Protoss +4 Expert
Profession: Zealot +6 Master
Exceptional Shields +2 Good
Reflex enhancements +2 Good
Not very suave -2 Poor
As you can see, this Zealot is a combat machine, specifically for close combat as Zealots use psi-blades in combat. He has not received additional psionic training beyond his natural talents, as he focuses exclusively on combat. That also means he isn't of much use outside of it, as his weakness in comversation shows.
For most combat checks, he would have +10 to attack (profession + race for psi-blades) and +10 for defense (profession again, but no race, as he has no psionic defenses. The remaining +4 come from his speed and above-average shields.)
That's all the info for creating characters. I'm looking for 2 to 6 players for now, if there's any interest or questions, feel free to post.
