I hear you, Tomas. Private is better. I think that was harder to do in this case, though, since Avahur gave his initial criticisms publicly rather than privately.
As a newbie GM, I have a keen appreciation of just how much work goes into it. PT isn't exaggerating when he talks about hours of preparation.
The folks who run games here aren't paid for it. It is a free service.
Therefore, an attitude of gratitude is appropriate.
When a player instead chooses to (publicly) respond with "ABOUT FREAKEN TIME!!!!", or "this is starting to sound stupid", or "uncool", this does not make for a win-win situation for GM and player. If we (GMs and players) can't come together, interact constructively, and have fun, then what is the point? If GMs don't feel appreciated, they will get burned out. And if you burn out the available GMs, and use up the available worlds, then your ability to game will inevitably end.
Avahur may well profit from being in more worlds where choosing to violently act before thinking through all of the angles doesn't kill you off right away. But in the "Joining the Worldwalker Game" thread, PT states clearly and up front (bold font added):
Playtester:
I prefer you post in the first person, as that is easier to read, and allows a better understanding of the internal debate, but it is not necessary. I don't like profanity, and I am not fond of vulgarity. I also don't like pointless "I kill it characters", not that I've had a problem with that with any of my players on this forum or my other forum at GamingOutpost.com. I prefer thoughtful, introspective, and bold characters.
No one can say that they weren't warned...
So this free service is here, and the terms of service are clearly stated. I believe that those with an attitude of gratitude will survive and thrive here, and make the experience a pleasant one for both GMs and players. But I suspect that those that don't, won't.
