No, I have never been asked to leave a game that I played in. Yes, I was booted from a PbE-Mail game... The GM wanted to play a "Strive to Become First Level!" game, where you started as kids about to go through their "emancipation", and seeking to find someone to mentor them. He had all kinds of things like teachers beating you for "impertinence" for asking if any non-humans lived in this land before man, getting into trouble for talking to a girl, etc. The game stated that he wanted you to "experience the thrill of casting your first spell!", but we never got that far...
My PC was an orphan rogue, working with the pig-tender, who wanted to be a Ranger. There were other PCs in the game, but apparently the GM was running everyone solo, at first, so I hardly had any interaction with them.
The kingdom was
Chaotic Mean, IMHO, except perhaps for the one Prince that I met, one day, along the pig path (!?!). Anyway, as "emancipation" approached, my PC was trying to find a "Ranger", and the Prince told me that so-and-so could train me, but that he HATED Rangers, as that was what their enemies in the war called them, and so not to mention "Ranger" to so-and-so. He called them something else, in his game...
So, I went off to find old so-and-so, and told him that I wanted to be a woodsman, adept at survival, stealth, tracking, infiltration, and spying, better than any Ranger in the enemy forces! Then he roared at me, asking how dare I mention them to him, that he wouldn't train me, and I should get out of his sight! (I also got an E-mail from the GM, saying "I
warned you not to mention them to him!")
Reacting like a 16-year-old (which my PC was), I took him
literally, and ran around the corner of the building, where he couldn't see me. Then I considered my options. I could go to the guy who trained the Fighters, and at least learn that much, or... I could go off into the woods, and learn to survive on my own! I didn't expect it to be easy, I figured the GM would have it rain on me, etc., but it seemed the best way, so that's what I had my PC do...
The next time I logged in, the game menu was gone. I E-mailed the GM, asking if I had been removed, since there was no "The Game has been discontinued..." notice, and he replied: "Yes, you were! You are sh
t!" Frankly, I didn't mourn the loss... I just wonder if the other PCs got the same sort of trearment, and how long the game lasted!
