I think deep down, all of us are trying to "win" at D&D. It's at the heart of min/max behavior, fire giants masquerading as kobolds in Dragon Mountain, and pit traps that contain green slime, skeletons, spikes, and crushing walls (all at the same time). We say we're playing as a team, or to advance the story, or to develop characters, but really, we just want the magic sword of destroying every monster the DM dreams up. As someone who has DM'ed in 90% of all games he's played, I want to tell you something. I'll give you the sword. But then I'm waking up the tarrasque.
