Okay, dude, let it go. That post was not about you, so stop trying to take it personal. I don't even know who the hell you are and wouldn't waste my time calling you anything, implied or otherwise.
Don't want to play because you don't get on with some other players? Totally legit.
Don't want to play because you've tried the system and it's not your thing? Totally legit.
Don't like the setting or the premise or some other storytelling angle? Totally legit.
Don't want to play because it's not something you're used to and you don't want to take the time to try something outside of your comfort-zone?
Casual.
Elitist? Damn right it is. Let me tell you something you already know = A player runs one character. He reacts to situations and improvises his way through. And when he gets stumped or is just having a bad night, the other players can take up his slack.
But the GM runs the entire universe and everything and everyone in it, even down to how the laws of nature work. He has to run dozens, sometimes hundreds of NPC's that are above the level of movie-extra quality. And he's got to have a plan to deal with every squirrely thing that the players will come up with to overcome the days or weeks of planning he's sunk into a single game session. Improvisation only gets you so far, so a GM better have a dozen backups ready to go. GM's aren't allowed an off-night or to get stumped, and there is no one to pick up his slack. A GM is expected to be on time and on target from beginning to end.
And he has to do all that in such a way that he can work
with the players to help
them tell a heroic story of derring-do.
Barley 1 in 20 players ever gets the skills to be a halfway decent GM. Fewer than 1 in 1000 ever master it. And that right there is what make us the fracking
Elite
.
That is what the Players at my table expect from me, and they in return give me the respect that I have
earned from them. And any
Casual that doesn't like it can go play Hello Kitty Online for all I care, because he's got no business sitting in the company of real Players.
