So the AI offers me a system if I call off my war. I say yes, because I know I'll save some tanks and have fewer collateral damage. I take a few turns to gather up my troops, reorganize a bit, move my fleets to a more advantageous position. A few turns later I just attack again, having benefited from the temporary ceasefire...
Seems to me like there should be a 10 turn window where you simply can't attack. Or maybe a reputation penalty if you break peace treaties right away? I might have missed it, but I don't see any such penalty. Anyone know if there is anything to prevent you from abusing the AI like that or downsides to doing so?
