Well, I have used variants of those kinds of messages in a different game. (Firststeps, was filled with all kinds of devious diplo, convincing one nation I spoke for more than myself etc. Somebody putting up a global he heard I would approve of. I didn't. etc
).
But certain mistakes are just common errors. I tend to be rather friendly about those things as I know how easy it is to make a mistake with the not so friendly UI. (And doing a turn all over again SUCKS. had to do it once in the late game in one game because I ****ed up with a cursed arti. Not much fun). I try to be noble. Not all the time of course, but within reasonable bounds. And I doubt that the 50 air gems can win me the game
.
And anybody who is still dealing with Ermor at this phase in the game deserves what is coming to them.
