Interested, been wanting to RP persona for a long time but every time shes noticed one it ended up not getting off the ground. 

Could try and help with co-gming stuff too if you need one, thought of making a persona rp a few times in the past but never did it so could dig up some of the ideas from that to try and help cobble stuff together. [s]Plus she just loves world building, so theres that...[/s]

Anywho, as for general input, would think a new story(like the third idea) would be more fun then just rehashing p3 or p4. Would say not having a wild card would be the best bet in general as well, in order to keep players on more even footing. No huge opinion on multiple persona per arcana for all characters, might be a little complicated allowing everyone multiple personas though. Having a single persona per user(and maybe an evolution at significant development points) could allow for it to be more symbolically related to the character as well. Either way could probably work though. 

If you do end up going the way of p3/p4 AU she'll just put in a vote for p3 since thats her favorite. 

Anywho, love the hell out of persona, would love to actually, finally get to RP it. 

[s]She can also volunteer her hand at making some pretty graphics if need be /photoshop nerd[/s]
