+1 to all these (don't be a dick, have fun, remember these are friends)
But, the absolute most important thing you must do as a GM, IMHO is NEVER write a plot outline. Flesh out your setting, create interesting NPC's with their own goals and motivations, but don't you ever write a GD plot outline...
To paraphrase South Park, every time I see a GM do this I want to shoot him in the twig.
Move the world along, not the game. Make your NPC's try to fulfill their goals, make stuff happen, and describe things that happen where the PC's are - it's the Player's duty to find the plot they want to follow, not yours. If you have an army march through the town, a plague infest the town and then an undead NPC proclaim himself king of all this land and the players are content to sit in the tavern and drink and flirt with the barmaids the whole time, let them.
Your job is to create and move the rest of the world along, it's up to the players to get involved in the world, find the story they want to take part in, and follow through with it, if they don't, let em sit and rot.
Heh, totally opposite to me.
Your world will never matter as much to the players as it does to you. You have a choice to make. Is your world more important to you than your players or not?
For me? An engaging story trumps any amount of scenery every time. Make sure that your campaign is the most important thing you spend time on.
Agreed.
