Alright, Sage Mode activate:
I hate to call meta game since it was a collab, but I wanna talk about preserving the character IC and leaving OOC knowledge out of it. My first concern is knowing about one another and reacting to one another's presences. When I judge how appropriately/how good you guys roleplay, I do it based on character sheets. So far, Iktomi (excluding kage powers) should be the most scary, badass mothahfuckah out there, since I approved it. The only other characters that I would expect to meet him like that and not at least feel NERVOUS let alone SCARED are Ariela (cuz she a freak), Victor Esteves (cuz he's too boss), Ishigo (cuz batman), and that's probably it. Even Arianna was nervous when she met this fucker - and he's like her childhood friend. It's kinda like the worst flavor of metagaming: your character is a total badass, fearless, super clever mahfuckah that isn't afraid to fight JUST BECAUSE YOU KNOW ITS JUST A ROLEPLAY. Secondly, I'm going to assume Lost let you guys "know about" his character. If he didn't, then DON'T do that. Just making this clear, I'm not accusing. Reading that collab made me remember that I forgot to make this point before. Basically, I accepted Iktomi's CS and it included how he was a super secret underground mahfuckah. BY READING HIS CS IN REAL LIFE, YOUR IC CHARACTER DOESN'T SUDDENLY ABOUT IKTOMI. A good way to go about this would he either ask Lost (which I'm assuming is what happened since it was a collab) or PM a GM to review CS's and determine if yor character's knowledge would be plausible. Nah mean?
Lastly Character interactions should be things BOTH players agree on. If Joe doesn't agree to Bob suddenly exploding everything and killing his grabdma's dog, then you know what Joe does? He contacts a GM! He describes the situation and the GM will settle it out. I want to enforce this now because eventually... Believe it or not...
Niggas gon die. And believe it or not... It might be a player trying to kill another player! So either agree on it, PM a GM, or I turn this into a table top roleplay with stats and shit.
And remember: NONE OF YOUR CHARACTERS ARE PERFECT EXCEPT FOR FRUITSTAND. ROLEPLAY FLAWS TOO! CHARACTERS GET SCARED, MAKE MISTAKES, etc.
