well said both of you.
The mechanics should encourage roleplay, for example by having stuff to do as a group and forcing/encouraging players to interact with one another to accomplish goals.
In PS, I think this may end up coming about as more and more skills are developed. The more options there are, the harder it will be for one character to gain mastery in all of them. A set of limitations is I think necessary in obtaining this goal, which is why most games which fall under this genre have specific class builds. The classes have built in advantages and disadvantages, which makes grouping up necessary.
Planeshift has thus far avoided setting classes for the ideal of free character development, but maybe, by the endgame, when the number of options for development grows and grows, it will reach a point where a mastery in all areas is too great of a challenge, and a limited focus in development will become advantageous. It's all about balance.
I'll agree that the ties between RP and the mechanics are basically nonexistent. It's as much a fault of the developers as much as the players. Speaking for myself now, I typically only use mechanics as a sort of loose foundation when RPing. The mechanics just aren't detailed enough to express the actions of my characters, but I keep in mind their skill levels, knowledge in certain areas, to dictate what they are and aren't capable of. At the same time, I am guilty of creating alts that, for the sake of story, are masters of a skill set, although I haven't spet a single second developing that skill set through gameplay.
That might be one way in which the article doesn't quite fit Planeshift, or Planeshift doesn't quite fit the article, is that there are a number of players who use the game as a setting or medium through which to tell an interactive story, it's our responsibility to create the narrative out of the mechanics.
An area of development that i would like to see is a set of tools for players to use to run an RP. In table top RPGs, you have players who are DMs and players who are PCs. They both must follow the same set of mechanics, but their roles are completely different. In PS, we only have the PC role to work with. Some players are capable of running RPs through the PC role well enough, but we could really use more tools towards this end.
