so in short, IMHO detailed action and and graphic violence is a good thing, too much or too little is a bad thing, and substituting gamist narration mechanics for actual charts or specifics is the worst thing.
To make sure I'm understanding what you're saying, please explain what is wrong with the following exchange at a game table:
Player: "Yes! I rolled a 20!"
GM: "Awesome. If you want to turn the 20 into a critical hit, spend a narration point."
Player: "I'm totally doing that."
GM: "Okay, you get to narrate your criticals, so take it away: how do you maim him?"
Player: "I freakin' smash his skull with my hammer and his eyeballs pop out and his brains goosh all over!"
Other players: "Awesome!"
GM: "Alrighty, that orc is quite dead."
(As an aside, will you please also do us all a favor and expunge IMHO from your online vocabulary? You've demonstrated repeatedly on these very forums that there's really nothing H about your O. Having an O is no problem, of course--everything anyone writes on a web forum is by nature their O, and need not be labeled as such. Calling it H just makes you sound juvenile. Thank you.)
