The Good End of the campaign was my character (the norse neopagan berserker who ended up some conglomeration of Odin and Tyr) fighting his way to his Evangelion after the last Angel attacked in the middle of him getting tried for war crimes, getting in, fighting the Angel until it was just outside where we kept the Seed of Knowledge.
Then, to keep the Angel from getting it, I ate it.
Then I ate the Angel's core, which, as it turned out, was the Seed of Life.
I then proceeded to, using these awesome powers, merge with my Evangelion and initiate my own Third Impact. Over the campus of what was once MIT grew a great tree, taller than many buildings, reaching up to the edges of the Earth's atmosphere. This tree, this World Tree, Yggdrasil, was the manifestation of humanity's collective unconcious, and with it came immortality and wisdom for all who wished it. My Pilot, in human form, walked out, and created with the last bit of the power he got from the Seeds of Life and Knowledge the NORNS, biological computer systems to allow people to interface with the knowledge of the World Tree.
And, for a time, there was peace and prosperity on Earth.
Then the Angels returned, and we started a game that was basically Neon Genesis Battlestar Galactica, with the remnants of humanity fleeing from horrible Angelic monsters in a world-ship, carrying the seeds of life, knowledge, and the world tree with them. But that's another story alltogether.
