In summary, is it better to velvet rope, or is it better to kick players out? And, if somebody's a jerk at your dinner party, how much attempt at communication are you really obligated to do? Because, I think, for a lot of us, it's less than you guys seem to think.
Great point and something we should've elucidated on. The communication we advise is about quality, not quantity. Have good, effective communication up front- it will save a ton of time in the long run. Head off the problem when it first arises, don't spend 10 minutes every game just putting a band-aid on it.
I'm convinced that most gamers, when they "just talk to" their fellow players, do it in a way that adds to the problem, not heading it off. So it's the same amount of communication- perhaps a bit front loaded, but saves a ton of time, energy, and heartache in the long run.
