There's gamism, simulation and story-telling. Lots of questions have different answers depending on what people want from the game.
eg. A question about mapping - in dungeon-crawls it's essential especially that DM is supposed to require players to find their way in the maze. - in story-telling and alike it's the other way around - players shouldn't bother drawing maps of cities assuming that every non-retarded dwarf/human/elf will find his way (and if not, the GM will say so).
Maybe we should add tags to answers that would refer to 3 common attitudes.
What do you think?
