Thanks for the link. It's a fun little article. Can't stress the importance of number five enough - I can't recall how many sessions have grinded to a halt because the rogue couldn't keep his hands to himself or the Paladin got self-righteous about something. Nothing worst than having to hold that Orc ambush off for a few minutes cause your busy stopping the party from killing itself.
...or ya know just launch the ambush anyway
I know this thread is old now and the post I'm quoting was like six months ago but I wasn't hear then so I figured I'd throw in my two cents and disagree. PvP, when done right, can be excellent. for instance, once, I was playing a neutral evil gnome sorcerer who was following the party around for his own gain and just generally being a dick to people. after a fight, I was mouthing off again because the character was a cocky bastard, and the barbarian walked over and one-shotted me. the character I'd been building was dead, and no one in the party gave a ****, because he'd been a dick to all their characters. we hadn't discussed pvp beforehand, so I had no idea that could happen. and it was one of the best experiences I'd ever had roleplaying. this is years later, I don't even roleplay at all anymore, and that still sticks with me. I wound up rolling up a new character who was a druid from the barbarian's tribe and his childhood best friend, there were no hard feelings, and it was awesome. part of party dynamics has to be conflict. you can't all get along on everything, that's not realistic. and sometimes, the tension is just gonna boil over. as long as it's character-driven, it's all good. it can get irritating when the players are actively just looking to start ****, though, I guess.
PS: in fact, of the three D&D events that will always stick with me, two involve my character being murdered. the other time, I was playing an assassin who had cut out his tongue so he couldn't speak, and the party misinterpreted an action and since I couldn't explain myself they killed me. the third event is a joke.
