Actually went through another playthrough. A second Transcendence victory, surprisingly enough, with Colonel Santiago of all things. It was a mostly peaceful playthrough as I mostly kept to my own island, but sometime in the midgame Diedre decided to be especially obnoxious and began to harass me with Needlejets from across the strait, destroying some of my noncombat units in the area. Eventually though I picked up the tech that allowed for support-free units and just spammed elite helicopters ad nauseum from my capital, all of them interceptors, so I became more than adequately protected. As in the other game, I probably could have tried to take over the world more directly by the midgame, but that took too much time and effort. I also could have gone for an economic victory by just getting scads of energy, but that would have been no fun.
Still baffled that I managed to play Santiago as a peacenik and succeed. At least she wasn't Miriam.
