Alright, cribbing off of sonofccn's "A nonserious situation of mayhem" thread over on Starfleet Jedi, I've decided to make my own "evolving situation" thread.
Congratulations! You've found that you've woken up in the BattleTech universe in the year 3055 AD. Somehow, you've managed to find yourself ruling over all five Inner Sphere Successor States (Federated Suns, Lyran Commonwealth, Capellan Confederation, Free Worlds League, and Draconis Combine) AND all seven Great Clans (Clan Wolf, Clan Jade Falcon, Clan Ghost Bear, Clan Nova Cat, Clan Smoke Jaguar, Clan Diamond Shark, and Clan Steel Viper). You've got an approval rating of about 97%, and the worlds that were devastated by the war are currently being restored.
The bad news? Well, every so often, new an unexpected threats will emerge, adding an increasing amount of... headache... to the galaxy.
5 years from "now": The Sino-American Alliance (Firefly) appears near the Periphery.
10 years from "now": The Terran Confederacy (StarCraft), as of just before the events of the first game materializes just outside the territory of the Capellan Confederation.
15 years from "now": Fleets of Ha'taks show up in the Draconis Combine, signaling that Goa'uld System Lord Apophis (Stargate) has arrived.
20 years from "now": The planet Mandalore (Star Wars) and all its colonies, as of Season 3 of "Rebels" appear at the Capellan Confederation-Free Worlds League Border.
25 years from "now": The Klingon Empire and Romulan Republic (Star Trek), as of four months after the Iconian War, materialize to the "East" of the Federated Suns.
30 years from "now": The Protoss Empire (StarCraft) (and Dark Templar tribes) as of just before the events of the first game, arrives near Clan Territory.
35 years from "now": The Humankind Empire Abh (Crest of the Stars) appears right at the Lyran Commonwealth's periphery border.
40 years from "now": The Yuuzhan Vong (Star Wars) begin their invasion.
45 years from "now": The Borg (Star Trek) arrive en masse, with assimilation on their mind.
Your mission: Either through diplomacy, force, or trickery, ensure that at least 51% of the population survives the oncoming clusterfuck. How do you do it?
