I respect you hanging in to the last planet
Turn 13. I sent you a message for a NAP you responded with the 1900 line.
Turn 15. I sent you a list of my Planets next to yours and my willingness to defend them, you failed to see it for some reason. I stopped Colonization out of respect and had a idea what Planets you owned or should have owned.
Turn 19. Your Cold Pain shows up over Planet 480 (one Planet in my reply) and is destroyed, you said said it was verifying, I replied "Verified".
Turn 26. You sent in at least 4 Vickies plus mine laying Coldpain's and take one of my Planets as I GA a couple of yours to open a front with the COM.
I realize you were boxed in by the COM and me and had to make a choice with the COM and I, and did see Virgos in your Space as in time you ended up gifting your fleet and Planets/SBs to him but really tried to work with you, In hindsight it slowed my Colonization perhaps we can work together in another game.
As for doing it alone, your 500 ly front was one of many,
I was Hostile to the Pirates and invading him on a 700 lys Hostile front,
300 ly Hostile front with the COM,
200 lys uneasy front with the Borg, Crystals came in with a Falcon and helped me out a great deal and he himself had a couple thousand Lys of Hostile front himself.
