But, in traditional RPG's all of your choices are presented by the GM/DM. You have absolutely no control over anything. If I choose to have my character go over that hill, it is entirely up to the DM to decide if there is anything to do on the other side of that hill. At no point, in a traditional RPG, can I have any impact on what I will find on the other side of that hill. Thus, as a player, all of my choices are passive. Or rather, at best they are reactions to whatever the DM presents me with, which is exactly the same thing.
I cannot change the world through my actions since all of my actions are limited by what the DM will allow.
Now, I do 100% agree that this is one style of roleplaying. Certainly. But, it is passive/reaction roleplay. I have no options for changing anything other than whatever levers and buttons my character can push. And every single one of those levers or buttons must be given the tacit or explicit approval of the DM.
Therefore, by your definition, the DM cannot roleplay. After all, he is doing EXACTLY what the players are doing in my scenario all the time. He is changing the scene and the setting to suit his own purposes (presumably to make the game more interesting). Exactly what the players in SotC are doing.
So, if the DM is roleplaying, why am I suddenly not roleplaying for doing the exact same thing?
In your example of roleplaying, what exactly do the actions of the characters mean to someone in thier role?
The examples you gave represented a mechanical means by which a player contributes to the group story. If the given role of the player is co-author of general world events then that role is quite different than the role of someone living in that world. This is an example of storytelling from the perspective of various players who are all co-creators of the universe.
Ariosto touched on an important part about the DM roleplaying. While portraying the persona of an NPC, the DM needs to take care to portray that persona faithfully. This means that big dumb creatures should act appropriately for thier intelligence level.
If a player feels limited by the range of available options because such options do not include influence over the world beyond what the character is personally capable of then the player is simply not satisfied with being a player.
