Without an "Ignore" command, Demigod is the first game in my life I've had to make a little "ban list" for. It's only got a couple names on it, but, the very first ones I put on were Apika & Belier. I did not make a note of why I put them on the list, so I can't quite remember playing with them, but I did underline their names twice, and put exclimation points after them too, so I'm guessing it was not because of their spelling errors in chat. . .
And I'd like to add, in agreement with the OP, that I don't really care about winning (too much). I lose at DoWII a lot, but it's a "fair loss", so I just shrug it off and try again. But with DG, and usually playing Pugs, a win is rare, and when your finally about to win with a pug, and the other team just quits (AND they don't get a loss recorded to boot), it really starts to lower your desire to even play after a while.
