What I really hate is when an opponent, where he has like 20hp and he is poisonned for 50, quit on it's very last turn. This is stupid because he could just press 'space' and let me then press 'space' and it would then be over. But no, he quits, letting me wait a huge 70seconds while it could take 5seconds. I don't quit, even if I have completly no chances.
