You don't need to have the appropriate skill in order to attempt something; you can roll Stat + 1/2 level mod. The skill list isn't restrictive, it's a list of things a character can focus on. I think.
Oh, I agree... but players will tend to favor what they are more likely to achieve success with, and those are trained skills.
As an example (and one I didn't think was a good call) in the recent Robot Chicken D&D games I see one of the players (Bluebell I think) shut down by Chris Perkins when he tries to do things with the Acrobatic skill that tend to fall under Athletics. I believe it's in the ice episode he even says something to the effect of "Can't I flip form wall to wall and get up onto the room" and is told no by Chris. Is Chris wrong or a bad DM... No, I don't think he is for making this call (though it's different from how I do it in my game) but I think it's a good example that not everyone is as lenient or narratively focused when it comes to skill use as others are. it's because of this variation in playstyles that I think perhaps more examples and information on what skills can do for both players and DM's might be a good thing.
How I do non-combat stuff: figure out what level the opposition is (1-3, 4-6, 7-9, etc.) and give it a DC. Herding mules? Use the level of the terrain and there's the DC.
Anyway, check it: http://www.enworld.org/forum/4e-fan-creations-house-rules/270905-fiction-first-skills.html (I think I've revised some stuff since then.)
Ok, I can get with that... and I personally have the rule of cool in my games now (a variation of Exalted's stunt system)... if you can describe it and it sounds cool... then you can use whatever skill(s) you want to accomplish something. but I guarantee there are some DM's that will play it by the book (and in no way am I saying they are wrong for this) and if the book doesn't give them or their players the tools and guidance to adapt and mold the skill system, they probably won't. I know I didn't when I first ran 4e and it was one of the reasons my players and I didn't like it at first. But you live and you learn.
