"Or you just have fun with what you're dealt, do what you can, and when you die, you die happy."

Hey, I've no problem with that but it's not fun. Fun in a TBS game is derived from ability to nurture your investment (nation, state, space colony etc) and see it evolve. It's ok to fight wars, it's ok to lose them but it's not ok to have significantly less chance to see your nation grow from the start. A RAND game played with a weak nation sees you getting pounded from early on and usually from many directions. The problem is not to die happy it's how you suffer all the way there. Usually I end up wishing my nation's death would come all the sooner since at that state my turns seem futile. I keep playing out of obligation for the other players not to create a power vacuum.

I don't think this is going to work. What if three nations want to attack? They have a lottery? How do they even know they are all going to war that month? How do you even know when a war is starting? You'd have to declare all wars in advance. What if secretly allied nations collude to have a 'pretend' war, preventing themselves from being attacked? What if your only avenue of expansion is through a nation that is already at war with 2 other nations?

Yeah, the idea is not good. However I still think that the direction for a remedy is not to totally ban diplo but rather find a way to limit it's abuse. I'll give it more thought, maybe I'll come up with a better suggestion.
