Lot of crashes too mid and end game , and you need to disable AMD features to make it works, games is really janky and unbaked.
Plenty of exploits , for exemple when you enter a war you only have the option to end it, nothing to negotiate, no gains except what you already took . However you can offer to end war while negotiating with a completely different empire not invovled in the war, and the price to end war is absurdly high , you just exchange that agaisnt all their techs and the mining stations they are selling...Then you can use spy to steal tech super easily.
Game punish you heavily for not automating , you will become mad if you dont. Fleets take so much time to move , refuel and invade ,you just better automate and forget about it , just clicking on the advisor attack sugggestion. If you think you will pick one or two and do it manually , the ships will enter in combat one by one, or not at all,sometime getting stuck, sometimes not jumping, sometimes getting low on fuel without apparent reasons .
I tried to fullfill human empire campaign goals and get the most defensive pacts ever . Never managed to get a single one of them despite civs being euphoric towards my empire , having the ancient governement type, having the diplomacy researched.
