So I can name my character "Chunt the Flatulent" and my family was killed by orcs and be done with it. I wear a pink hat with peacock feathers and I forgot how to cast burning hands when I learned fireball. I have a peg leg, my tabard is neon orange, and I only speak with twelve words (yes, no, maybe, poppycock, cheese, one, wood, inconceivable, cow, moist, placate, roll). I run around in circles when I'm bored. I hate dwarves and will attack them on sight. I won't use weapons, and bracelets are too constraining (too much like the manacles the town sheriff uses when I get a little tipsy).
All because this game is like poker, and roleplaying decisions have absolutely nothing to do with the mechanics. Right.
Perhaps I want my roleplaying games to have some bearing on my roleplaying experience, and that playing chess, poker, Magic, and/or WoW in tabletop form is not really appealing to me. If the system doesn't make some concession to the fantasy worlds that we are pushing these characters through, then it is not an RPG, and is instead a board game, like Hero Quest.
