So, how much is the limit to Fourth Wall breaking?

[Deadpool]

Since I'm the local 4th wall breaker here, and haven't had many complaints over it, I guess I could help.

Really, its walking on a tightrope. You can have your character aware of his own origins, and be aware that every character he runs into isn't a real person (rather a character being controlled by another source).

Try not to go too much into knowing he's in a 'RPG'. I do it with Deadpool, yes, but you'll never see me just do a whole post or thread about knowing about the Omniverse--I like to sprinkle it in, to add to the humor.

It's basically a trial and error thing. Try to be creative, but just don't try to do too much. Also, you could always ask a staffer (probably an admin would be best) what their comfort level is with 4th wall antics.
