Legend
In TV/movies/etc., there is a dramatic rule: if the audience sees the planning, then sees the action unfold entirely according to plan, that's generally not entertaining. Either the audience doesn't see the planning, and learns the plan as the protagonists execute it (possibly with voiceover, flashback, etc.); or the audience sees the planning, then sees what happens as the plan goes awry. Since the players are the audience, they don't have the option of not seeing the planning...
I can't remember where I read it, but there was one group of Spycraft players whose preferred mission plans were termed "burrito plans".

Basically, they'd plan like heck to get their operatives inside and to the mission objective as quietly as possible, but their plans for getting back out again didn't take stealth into account at all, instead concentrating upon distraction, suppression and superior firepower - because they knew that, nine times out of ten, there'd be no way things would go to plan long enough to make a quiet exit, so why waste time planning one?
