Just a few extra rules I thought up.
No Killing. Unnamed, faceless NPC's may be killed, but not major characters, or taken characters. Someone else may want to take up the character, or they may be important to another story.
You can go anywhere within the galaxy except planets already known to be destroyed, such as Krypton, although if you have the ability you may visit the ruins or asteroids.
You are your character, so act like it. Talk like them, use their dialouge. Do not exaggerate your powers, or pop-up here and there without explanation. BE Your character.
Several stories can be going at once, and you have the freedom to interact with other characters.
You must post at least once every two weeks, though it is preferred that you post more. If you go two weeks without a post without prior notice, your character is up for grabs.
Be serious, no slander, or impractical actions from your character. Example; "I found a crystal and now I own the world! You're all my slaves!"
