I just wanted to say great job, Devs! The new Diplomacy AI is a lot more challenging than normal!
My friend and I just played a game a few nights ago, a 2v2 vss a normal and a hard AI. Usually we stomp two hard AI's into the ground, but we wanted to relax and try out the new expansion.
Well, everything is going great until the AI decided to COMBINE its two fleets, attack my planet with the large one WHILE simultaneously outbidding me on the pirates, and also sending two smaller fleets to my planet and one of my friends.
In about 10 minutes I lost 3 planets instantly, and most of my starting fleet (and my VNV Egg ).
Well, we kicked our factories into high gear and ended up winning the game, but it was great having an actual challenge and being able to message "holy shit" to my friend as my planet got gang-raped.
I love it, great job guys.
