After many more hours of play this weekend, the Kohr-Ah started wiping out all of the other civilizations. Oops. I guess I took too long. That made some of the quests a lot easier, since I just had to visit the planet and pick up the item I needed. Of course, it made some of the quests impossible, too, so I decided that I was done playing the game. I removed it from my computer and skimmed a walkthrough for the game. Glad to have that out of my system.
