Again, trying to move beyond the whole "Purge" topic, since I had to flush several of my current WIP, I'm now considering my own adult-only variety to those same stories.
Obviously, they wouldn't be the same as the originals, yet they'd retain most of the same story elements. Thus while the romantic relationships would be strictly adult, the teasing friendly banter from their children would still remain, virtually the same as before, which would then allow the same teenagers to carry on their own affairs off-screen, so they too could better relate to what the adults are going through, and provide further grist to their friendly teasing banter.
But I've always appreciated both non-traditional plots and non-traditional relationships, so in this case, those adult relationships are also multi-person, each of who isn't a traditional relationship (i.e. no one wants to 'get married' and settle down forever, as each has their own careers and thus needs more freedom), yet they still want a longer-term, rather than short-term flings. They just don't desire a marriage contract.
And, when the heat on the server's finally eases, I can easily resume the earlier stories, while also keeping the later, more recently developed stories. Plus, with more adult characters, you also have more younger teens for each, so you also have the teens commiserating, encouraging the adults to 'spread their wings' and further exploring their options, as they're all now further connected to each other.
Certainly an entirely different storytelling approach, which also creates additional new options. Just something to consider.
