Riporto alcuni estratti.
Il titolo:
A note to problem players: the view from the chair
Ma come, i giocatori problematici esistono? Non l'avrei mai detto.

L'apertura del pezzo:
I’ve been reading around the blogs and gaming boards the past few weeks about the problems that GMs have with their players. Strange thing is, a lot of them are very similar and revolve around the player wanting/doing something that conflicts with the GM and perhaps the dynamics of the group. Of course, the said player either does not think they are doing anything wrong, or if they do know this expect everyone else to adjust to it.
Ovvero: problemi simili e giocatori che non colgono dove stanno rompendo al gruppo.
Fare il GM è un lavoro difficile. -_-
The GM on the other hand has quite a lot more to do. They need to have their notes out and their books ready to be turned to the right page, as well as be ready to improv if the players slightly deviate from what they had in mind. Their dice need to be within easy reach and have room so they can be rolled (not an easy task). They need to set out the maps and the miniatures, remembering which one is which and how they are affected by various factors. There’s the various NPCs to keep track of (particularly voices, if they are doing any) as well as “off-screen” events that may or may not be affected by the player’s choices.
And that is all without going into an encounter, which is hell on wheels for a first time GM as there are so many things going on at once!
GM come responsabile (e solo lui!) del divertimento di tutti? Eccolo:
The GM is responsible to make sure everyone has fun, and this means not having one person dominant at the expense of someone else. This is a management issue that the GM always has to look out for and is usually (at least as far as I have read) one of the reasons that these problem players leave.
E, in chiusura, il richiamo al fatto che non tutti sono "Bravi GM
TM"
Of course, this all takes into account that you GM is a rather reasonable and understanding person. And not all of them are.
Ah, e qualche riga più su, un po' di vanterie su come un bravo GM riesce a fare i funambolismi, e lui ci riesce, quindi... -__-;
