Do you not have sufficient rules in real life to live by and be controlled by ?
Lets see, WHY do I play a game ?
1. Main reason to have fun.
2. To get away from real world rules.
3. Do others around me have fun when I play? I like to think so, as I try my best not to upset anyone, and be nice and helpful.
4. Do I RP, yes in my own way, [Point to note here, there are many ways to RP] trying to fit in with the settings and not god modeing, as that is a lame excuse for bad RP.
5. If I feel my character should die in a RP, then he does.
6. IF a player asks me for or to give advice, I listen and see if I can give advice.
7. Would rules for RP make me want to stop playing, SORRY but yes it I probably would, reason; My way is not always the right way, but I get along with almost all I talk to, as well as them getting along with me, so as I show respect for others and they me, so I see no need for rules at all, and I think the covenant is a good guide line to follow.
As for how YOU can help the GMs police bad RP, report and petition the offending player, that way with a brief detail the GM can go to the report and see what was said. [On report the last five minutes are logged, so please use it]
