I'm thinking it might be interesting to explore something inspired by Blizzard's old Project Titan before it was retooled into Overwatch. If I remember correctly, it had to do with players taking the roles of secret agents of rival factions vying for control of advanced tech left over from a (mostly) successfully repelled alien invasion. The RP itself could be divided into two phases, one of course being the missions everyone takes on, but the other would be their civilian lives. It's very secret-identity-based superhero-y in that way. I'd of course be fixin' to emulate the style of it as much as possible, if left up to me anyway.

Also, just wondering, but has there ever been a time when someone happened by any of these posts and thought "You know what: I'm totally gonna try and make an RP on this person's behalf"? Not that I'm offering, because I myself likely won't be able to do anyone's concept justice, but it's something fun to think about for me.
