Oh, no hard feelings. I guess it's imposible not to feel a _little_ miffed when after 20 days or so of work one's empire gets trashed so quickly and completely, but in the final analysis it's just a game. Well played.
The Xiati world was large with an oxygen atmosphere. If it was inhabited by Irha-Nrr, it would have been a domed colony and could only have held a population of 960M. But there were about 4000M present, so they couldn't have been Irha-Nrr. I guess it's an understandable oversight, but it happened to be an Irha-Nrr emotional hot button. When those people were wiped out was when I rolled over and gifted you everything; the Irha-Nrr would do anything to protect those lives, including surrender.
Probably why the Tzeech figured that planet was of such strategic importance to me.
The thing I "didn't buy" about the coup was that the general who took charge afterward was the one who was wholly responsible for the attack on my territory; it was clear you'd massed those fleets on the borders for a while previously (including in Vintidrin right after we'd agreed to make it a demilitarized buffer

). I'm assuming of course that you were laying the blame for it on him; if not, then the misunderstanding was mine.
As for my goal, it was only what the Irha-Nrr had been spouting off about to everyone the entire time; I just wanted everyone to live in peace with each other and not commit genocides and stuff.
Now that the surprise of my stunning defeat has worn off, I think things wound up ending quite well all things considered. I've developed the "character" of the Irha-Nrr quite a bit more in this game than I did in all my previous single-player ones, and I think that in my next revision of them I'm going to record the events of this game in their general history.
It would probably have wound up a bit of an anticlimactic ending if we'd just mopped up the AIs and then run out the clock, after all. I'm just sorry I wasn't prepared enough to provide more fireworks in the finale.
