I'm not sure what my answer would have been before playing this game, but I definitely now prefer both the Exterminate and the Exploitation avenues. I also am very open to the Diplomatic side of the game and have successfully worked a few alliances. Unfortunately, the Exterminate function of the game as it stands right now doesn't win games, nor does the Tradeing. However, if played right, I'm beginning to think the PK Warlord win condition IS possible, though it will be close. It also depends greatly on people ignoring their outposts and harvesting duties.
