I'll start out by saying that I would rather not be GM. But yeah, I finished Allegiant yesterday (my cortisol levels are through the roof), and ever since I've been having a real hankering for a Divergent-themed roleplay. I think the only potential problem would be how to get characters from different factions to interact enough to move the story along and to not leave anyone out, so there'd either need to be a lot of interest or a lot of characters played by a few people.
Thoughts? Ideas? I don't want it to necessarily be the exact same as the books, but it'd have a very similar storyline.

It could be something post Allegient where the inhabitants of Chicago have to deal with the aftermath and having to shift their perspective and stuff.

That sounds pretty good too.

I have been craving a Divergent RP since I finished the series a month ago. I suggest coming up with a sort of alternate setting for it where it is similar to the aftermath of Allegiant, where everyone can interact, but alter it to where the Factions remain in tact. Use some creative juices and we can come up with our own little story
