Turn 2411.3 Dinglehopper withdrew from game.
In the early part of the game he had attacked with 60 frigates when I had ~15 DDs!
Luckily my PD DDs I had made after he killed one system stoped the 60 frigates. After that my tech edge got biger and biger. In the end I think food contamination got his people to riot. It was an odd game.
