That is a tricky question. I am more likely to look at an Rp run by someone that I know that I am someone I don't. Why? Simply because I am better acquainted with their Gming strategy. Does that mean I will join it? No, it has to be something I am craving and looking forward to being a part of the story. (It takes a lot for me to join an Rp I am not running personally.)

Now, I am mixed to who joins an RP I am hosting. I love having a core group that I know and I can trust. Reason? I know they already know what they are getting into with me as a GM, I am not an easy person to have as a GM. Plus I know I can trust them to not try to pull any BS - Godmodding, metagaming, bunnying, etc. I do enjoy fresh faces in an RP, but I like it to trickle in instead of being a flood of completely new people. If I can get 1-2 new faces for every 4-5 trusted core Rpers, then I am good. Sure, it is slower when it comes to meeting new people but it works for me overall.
