TDM vs P&N

[Suicide Junkie]

I'm sitting with a comfortable 50% lead over the nearest AI, the Vaxin.

They start sending ships through my territory, so I cancel my treaty.
Then, during the next 10 turns, they proceed to Double thier score!

They tripled thier military force in two years, and now have one Cruiser or higher for each of my escorts.

Then, when they attack, they're loaded up with PD, so my fleet can't even scratch them with CSM's. Fortunately, I had a stack of 8 year old missile bases on the planet, and a load of troops which tipped the balance.
In the end, I managed to cripple one, kill the OA on a second (no internal damage), and drive the other three off. My losses were limited to a handful of troops on the colony, and some scattered ship damage.

Currently, the Vaxin are swarming around in my border system, and I need a large military convoy to push through to my military bases there.

And all that under the twisted physics of the P&Nv2.5 universe I am impressed.
