And, as time went on, my ad's for "Player Wanted" became more and more specific and less and less polite. To the point of it basically reading, "Look, here is EXACTLY the kind of game I'm running. Here are EXACTLY the requirements. If you do not match these, don't even bother."
And it worked perfectly. My current group has been together for almost ten years now. Longest group I've ever gamed with. Been fantastic. So, yeah, when advertising a new game, you have to be VERY specific. After all, you're going to spend dozens, if not hundreds of hours with a stranger. You NEED to find out if you're compatible at the table before you start.
