Where to even start with this story...
So I started in Pan-Germania since I'd seen that work well for people in the past. Brikguy started over in the Shire and mgb started... somewhere in the Western spiral arms I think, while Silva started up north. mgb, brikguy and I skirmished among ourselves for a while until we all eventually realized that Silva had taken the ridiculously OP northern spirals (COLETTE, FUCKING FIX THIS) and was sweeping down both the western and eastern sides of the galaxy. We forged a hasty alliance but it seemed like it was too late to do anything but tell one another that it had been an honor. Silva was holding Britannia for maybe two turns out of three; mgb and Brikguy were struggling to take it back from him, let alone take any of his territories away. By this time Silva had the western arms as well as the northern spirals, and was getting 17 reinforcements per turn. I decided that holding the south was hopeless, and all I could do was troll Silva as hard as possible before my inevitable demise. So I went through FELC and Assyria, which Silva had left more or less unguarded while he fought mgb and Brikguy in the Shire. Somehow I made it all the way to the Order of the Equinox, depriving Silva of his Northern Spirals bonus... at the exact same time as mgb took MASS and obliterated Silva's western arms reinforcements. The tide had turned, and Silva was forced back to the extragalactic territories.
I consolidated my holdings in the North while mgb took over the Western Arms. It wasn't long before I saw him turn around and start taking territory from Brikguy, and knew that I would be next. He had Iceworld and the Western Arms; my five reinforcements wouldn't be enough. Sure enough, he pushes into the USA while I'm busy trying to take Emeria from Silverdream. I make a deal with Silva: if he doesn't send his troops into Space Canada, I'll let him keep Emeria. He agrees and starts stockpiling troops to take the USSSR while I use my forces in Canada and Equinox to take back the USA and move the bulk of my troops into the Central Powers. Meanwhile, Brikguy is proving tougher than mgb expected, so Silva uses the opportunity to steamroll through the USSSR and into Iceworld. Between the two of us (and the fact that mgb and brikguy never really managed to form an alliance) we push mgb down to a single territory with 30 or so troops in it. Then it's backstabbing time.
I wait for my reinforcement card, then drop 20 troops on space Canada and roll into Emeria. "Dick," Silva says over chat PM, and I reply by posting
appropriate music. Silva uses his own reinforcement card to launch a counteroffensive from Praetoria and take Space Canada and Emeria. At the same time, Brikguy surrenders and mgb starts expanding again, grabbing his territories. The very next turn, I take back Space Canada and Praetoria using the troops I had in the USA and Assyria, and Silva ragequits. It's just me and mgb now. We both have reinforcement cards, we both have huge blobs of troops on adjacent territories, but only one of us has the single most OP region in the history of military strategy gaming granting us 5 reinforcements per turn from a position that's utterly unassailable. We trade attacks for a couple of turns and mgb continues to send out small squads to capture the surrounding regions, almost taking the entire Shire; but in the end, I reduce his blob of giant infantry to nothing and take Britannia for the win.
