Okay, let me put my Player's Hat on for a moment as this is a topic that I can only talk about from a Player's Eye View. One thing I've been noticing more and more as a player now that I've seen a few different Storytellers and Dungeon Masters at work is that I very much want them to keep control of the game.
Sure, I want to be able to immerse myself into the world and if there's an unguarded and unlocked door I want to be able to go over and open it (though I respect there may be consequences). No invisible clip brushes, thank you very much. And I certainly don't want a Storyteller to tell me 'No, no, your character thinks this' or 'Well, now your character loves him' unless there's a magical effect in play because, hey, all I have is my character as a vehicle for everything I do and if my character becomes a mere puppet then what's there left for me to do?
But I do want the Dungeon Master or Storyteller to retain control. I want them to lead us all into the game world, keep us focused, silence our OOC chit-chat with a glance, and rap us on the knuckles if we're being silly. They're the Alpha. For the game to work, there word has to be law. I want them to be comfortable and confident, able to take issues in their stride (bitching never works and just adds to the problem), and I want them to be able to take charge through tricks of the trade or even through grown up discussions on how this is a HORROR game or a HACK AND SLASH game and how we might be completely floundering and violating the very tenets of the game we so wanted to enjoy.
After all, no one wants to destroy their own toys out of stupidity.
But of course, I want them to do this with kindness, patience, and an understanding that it's really, really haaaard not to be stupid sometimes as a player. That the urge to be silly does come up, especially if there's a moment of boredom (which isn't necessarily anyone's fault - two minutes is a long time for me to do nothing) and that frustration can cause me to button mash in the hopes of somehow hitting the WIN button.
But yes, it's a big ask. I know that. But I certainly will thank you for it!
