I can't say I've ever had a moment of getting pissed off at a writing partner. I've had my share of people vanish or lose interest for whatever reason, but actually getting mad at one another? I've only had that happen a couple of times, but that was more of a personal thing rather than anything to do with game stuff. I can't really imagine getting mad at somebody for something that happens with a game, either it works out or doesn't. It would probably be different if I ever write with people with volatile personalities, but so far everyone's been very relaxed and understanding.
