I... am interested in this. Not a huge fan of SAO, and that's putting it lightly, but I enjoyed Log Horizon a lot (maybe even enough to go ahead and finish watching it some day), and I absolutely fucking adore Overlord, so this sounds like my cup of tea. I'll try to get something resembling a character sheet up in the next day or two.
EDIT: Question. How advanced is other technology in this future? Do they have space elevators, orbital cities or off-world colonies? What about asteroid mining and/or interplanetary commerce? Could PARIAH be played by someone living on Mars or in the belt?
The first part is up to Gowi because I'm not all that familiar with the extent of technology in the outside world but I can answer the second part. It would be a yes and a no (assuming these colonies exist). Yes, there could be servers for Pariah on these colonies but can they interact with, say, someone on Earth playing the game? No, it's more than likely impossible. It takes light something like 4 - 20 minutes to get to Earth (depending on positions in orbit) so if you wanted to say, move your character, you'd have to send an input to the server then wait for the server to move your character then send that information back to you. Unless FTL communication is developed, it would be impossible.
