With which races do you have played your first DWU game?
It was me playing humans with Ackdarian, Atuuk, Boskara, Dhayut, Gizurean, Haakonish, Kiadien, Mortalen, Naxxilian, Quameno, Securan, Wekkaru, and eventually a couple of human-dominant minor factions who became major players.
The Gizureans were by far the biggest threat, going neck-and-neck with me into the late game and surpassing me at times, not surprising since they're almost entirely geared for war.
I could only ever manage to get the Securans and Kiadians to form Mutual Defense Pacts, and boy did I pay for those, since they both pulled me into wars with the Boskara and Gizurean that I had to finish. I ended up subjugating the Boskara after the first war, then was forced to declare war on them again even though they were subjugated because the Kiadians declared war on them, yet again.
To be fair, both the Securans and the Kiadians agreed to declare war on the Gizureans when I decided it was Starship Troopers time, although I don't think they added a whole lot to the effort.
