Game masters need to develop the campaign setting, build the scenario, learn the rules - and they also need some decent social skills. More and more, I've come to believe most problems at the table should be solved outside of the game, with a frank table discussion. But it takes a bit of composure and a willingness to problem solve to lay it all out there and talk through a solution.
Here's some for instances: you often see criticisms complaining about how players have sabotaged specific campaign styles and victimized their game masters - players that balk at adventure paths, because they want to go off the road; game masters that admit to failed sandboxes, because their players didn't know how to take control and everyone just sat there. A competent GM needs to be able to discuss the parameters of the game up front, and then monitor when things are going sideways and take a time out to have an out-of-game discussion to get things back on track.
Negotiating skills are important. Negotiation is about conflict resolution, and reaching a solution that works for everyone - it's like the art of getting to "yes" you hear about in the business world. One of the big complaints about the older style of games is that they create arbitrary (authoritarian) game masters. Maybe that's a problem for teenagers. Good problem solving skills and negotiation skills allow the game master to deliver cooperative rulings that work for both sides - game mastering is another area where some life experience and maturity go along way.
Hey, I'm not just the president of the hair club for men, I'm also a client. I've had a few irksome situations in recent memory, cementing my tenet that a DM needs to be able to talk to headache players, ie, confront the mismatch head on. I've had the guy that wanted to treat the scripted, linear adventure path as an extreme sandbox, blatantly ignoring agreed-upon "missions" to hi-jack the sessions. I've had the guy that insisted the only character he wanted to play was that neutral evil half-orc assassin, who promptly started messing with the other players as easier sources of XP than the dungeon. I've had the guy that thought old school exploration was a quaint and interesting throwback to the ancient times; real D&D involved a fully laid out miniatures battle mat, with both sides set up on the table ahead of game time, so the session could always start with the first combat.
Most of these situations ended with the mismatched player finding a different game.
The indy-game term you see discussed about this whole situation is "social contract" - what are the implied agreements at the game table that define how the group is going to operate? I'd go a step further, and say what's important aren't implied agreements, but tacit agreements. Make those things verbal, express, and negotiated up front. And be willing to part ways with players that want something different from a game, and can't reach a middle ground with everyone else. A long term gaming group is like any relationship, and it's best to get those expectations out on the table right from the beginning.
One of my favorite lists of campaign and style preferences is still the original merit badges put together by Stuart a couple of years ago over on Strange Magic (original post here).
