Dannae!
Great question...I am so new to RP, but thus far have really enjoyed it and find that it causes me to look at some of my own personal quirks in ways that I might otherwise be able to avoid.
For instance, I enjoy the world of PS and the freedom to roam and explore but sometimes I'm not in the mood to interact in RP but wish to wander, ask NPCs what I can and find books to read. I have worked on some PL too, but mostly so that I won't be a victim (if that's possible in PS) and so that I can heal. Otherwise I usually look forward to running into a player that I have "met" in PS or to meeting new characters. I usually ask a lot of questions of other characters, trying to get a handle on just who they are and how they think...
I find that friendships among characters can be simple most of the time, but as in RL, there are some who are just not interested in being friendly. That is fine too, and makes the experience more realistic.
I have only been here a short while, so I have not knowingly formed any alliances that may work against each other and therefore my character. But, that too is like real life and being "the new kid in town". In time I hope to remember other characters more readily (looking the same can make it hard at first!) and keep our history more intact!
All in all, I would say I am here for the RP and have been more than pleasantly surprised at just how civil and generous other RPers have been. This is an amazing medium through which to explore interpersonal relationships "virtuallly".
Thanks for the question Dannae, and the friendship
