Hey. I've been wanting to run an RTD for a while, but I can't decide on a story idea, so...maybe you guys can tell me what you'd like to do. Here are my ideas.
1. Military/Espionage RTD: The year is 2012. You're all part of a task force comprised of various special forces units. Basically, you gather intel on your foes and sabotage their efforts. You infiltrate their ranks, assassinate high-value targets, support (or crush) rebellions, cut off supply lines, and do whatever else you can to stop your enemies in your tracks. You do what the average soldier could never do.
2. Mass Effect RTD: The year is 2184. The galaxy is united under the rule of the Citadel Council (except for the Terminus Systems). However, all is not well; humanity is at war with a race of synthetics known as the geth, and the Citadel has been heavily damaged by an attack on the Citadel by the geth (haw) flagship, Sovereign. Citadel space is reeling from this catastrophe, and now, less lawful types want to take advantage of this situation. An army of slavers, mercenaries and other criminal scum is forming in the Terminus. Nobody knows who's in charge, and that's where you come in. A Spectre (one of you) has been deployed, and s/he will follow Commander Shepard's example by forming a team of elite soldiers (the rest of you). You will find the leaders of this army. By killing them, you will cripple it.
3. Sci-fi Cold War, Hot War RTD: It is 2255, and humanity has finally joined the galactic community. However, unlike Star Trek, we do not run one massive alliance composed of dozens of different species. There are several different alien alliances out there, and each one has a different agenda. In fact, the galaxy is stuck in a cold war. There is a delicate balance of power, and tensions are high, but nobody dares to attack anyone, for fear of igniting a massive interstellar conflict...until one fateful day. You are all officers/pilots/marines in one of the human alliance's fleets, and your actions may decide its fate in the coming storm.
