Yo! So I've been playing the hell out of the series recently, and I've always wondered about how a few little scenarios might fare as RPs. It's an interesting universe, and Shepard's story isn't the only thing that's notable out of it all. See how much you guys like these.. if anyone actually enjoys Mass Effect here!:
Also, I have plots in mind for everything I've put down - even if they seem kinda empty, I do have plans...

Idea #1 - The Reaper War
That galactic-scale battle against genocidal AI cuttlefish-ships. Shepard went on a series of diplomatic operations in order to unite everyone against the threat of extinction. We saw destruction on massive scales across multiple worlds, but I felt war only got real for Shepard's crew when they hit Earth. The intensity, all those Reaper forces, Reapers themselves joining in the thick of the fighting. Imagine... What might it be like fighting for months on Palaven or Thessia? Perhaps as the Resistance forces on Earth? Brutal stuff, ...brutal stuff that could make for a pretty awesome war/survival RP! This idea would likely have the players as ragged defenders, civilians forced to fight even. Someone might even play a Reaper as an interesting perspective, serving as a hunter & main antagonist.

Or, maybe we could just ditch the planetary defence and be posted around the galaxy as a mobile strike team of sorts, like the Normandy's crew. Well, that's that idea.

Idea #2 - Mercenaries, Pirates, Smugglers, Vigilantes?
From the title you see where it's going. No endgame war. This could happen before or after the Reaper War, doesn't really matter which. We put a crew together. Scum, maybe just unlucky folks with the skills, need credits so badly they're doing dirty work for it. Be against the galactic law enforcement agencies and militaries. We could work for crime bosses, be hired by shady Council factions. That'd cover the first three categories anyway!

The galaxy could also use a good clean-up! Garrus Vakarian was a firm believer in just blowing all the scum of the galaxy away. Disrupting operations, hit-and-runs, assassinations... The odds are heavily stacked against a team of rogue lawmen, but that's what they'd have signed up for. Like any of these options?

Idea #3 - Black Ops/Spectres
The elite have no limits - get the job done, whatever the cost. Galactic security counts on the Spectres' lethality in risky situations. From derailing dangerous hostile operations, to changing the galaxy with a single bullet, these are the people who serve the Council in their own ways. What goes on behind the scenes really is brutal, but somebody has to do it...

For this, I was thinking of really throwing us all into the fire. I'd give us a threat dangerous enough to require a *team* of Spectres... Or a very high-skilled task force selected from each race's best forces.
