Scorched earth

[Baalz]

Yes, and to make things even clearer that this is an orthogonal discussion to putting up a good fight, my biggest frustration ever was an opponent giving up *before the first fight even happened* and turning all his efforts to destroying everything he had while I was waiting for the NAP to expire - I'm not talking about border provinces he thought he'd lose, he started pillaging his capital the turn I sent NAP notice. I'm talking about crippling yourself because you've decided your cause is lost and you are *solely* trying to reduce what the person who defeated you will gain after you're gone. Its really a matter of intent as obviously there is a lot of room for these type of actions as part of fighting to the last man. When you're saying "I'm doing this because you beat me and I therefore hope you lose". Pillaging the last of your population so you can giving large sums of gems/gold to the most likely opponent of your invader, inviting unrelated players to take your provinces while you leave them undefended, and razing your last castles are simply not part of fighting until the end as you are explicitly destroying yourself.

I do spot in this thread another justification, which is in the case that your invader is drastically more powerful than anybody else trying to bring him down a peg to make a more competitive game for everyone is really in everybody's best interest. That's a valid move, and I don't even really think anybody could be annoyed by that.
