Everyone seems to have a different definition of RP... however... the most common one i read about on the forums is a bunch of people sitting around the tavern or something. I've heard of GM events and how you should use the /roll to determine the outcome of whatever action instead of using absolutes. The problem comes in when you are trying to do something that other characters don't agree with. If i wanted to charge a toll for crossing the land bridge in oja to the crater opening, there is nothing i can do to force the character to RP. I cannot challenge him/her "physically" without permission, I cannot intimidate them into paying me 20 trias for passage, I cannot even get his/her character to stop and listen to me.
Am i saying that Uber characters should just sit around and pick on newbies? No. I am saying that if someone wants to play this kind of thug character, it should be allowed, but also that the newbie should be able to raise the alarm and have a group of people send the guy to the DR for picking on people. This creates a real RP environment where there are consequences for actions.
I personally don't care about mildly abusive or off-color comments made in-character. I think that is fine, but others are going to get upset by it. Does that mean that this type of language should be banned from PS? I don't think so.
I really think that if we could get a real economy going with a merchant or occupations, it would leave a lot more time for real RP. I have spent more than half an hour just trying to make it someplace to trade with someone for a weapon. While this may be realistic from a certain point of view, it was 30 minutes that i wasn't interacting with another living soul in-game. If i could focus more on my characters development instead of having to hunt down the people I need to aquire items from, it would help.
