1. ACTIVITY. For a role play to be successful, it needs players. Active players. Therefore, I'm going to say that everyone needs to update their personal journal once every two weeks and needs to at least respond to a post once every week. I have faith that people will find this interesting enough to do more than that, but that is the bare minimum.
2. DRAMA. I like drama. It makes for a good storyline. But please please PLEASE keep OOC drama and IC drama separate. You don't have to like everyone. You just have to rp nicely with them.
3. GODMODDING. Don't do it. It's rude.
4. CHARACTERS. With an rp like this, there are lots and lots of different characters. First gen, second gen, the media...anything goes. So my only real thing with characters is going to be to keep the character the way you created them. Don't randomly change their personality half way through the game for no reason at all. All that does is confuse everyone.
5. STORYLINES. I'm going to try to come up with some overreaching plot. However, the subplots are up to you. So mingle, get to know one another, and create your own little dramas. Feel free to pimp for storylines in the OOC community.
