Angel Beats is my favorite anime and my favorite world-setting. It's very close to my heart so I'll be watching this from the outside for awhile, because something like this has to be executed perfectly for me to be interested (not to be a dick, sorry).

If I can help, message me. I'm a story-writing machine, and an Angel Beats enthusiast. c: I suggest watching the anime if you plan to run an RP in it's world.
