[X]Alternate timeline
I would add that "pinpoint, surgical changes" are not our strong suit. This isn't a tiny roleplay of a few, dedicated players with similar goals and careful methodology, who can avoid pushing the figurative button if it comes down to it. Because if our options are "
kill Nephandi mecha-Hitler push the button" or "remain unseen," you know perfectly well that we'll go skipping right past the "die from terrifying amounts of Paradox backlash" bit and go straight to PUSHING THE BUTTON.
Hong Kong? We went in to investigate the sale of magical artifacts. We promptly found the building, snuck some agents inside, had a perfect setup for a
Mission Impossible-esque spy technomagicalthriller...and then Jamelia put on her mirrorshades and kicked in the front door to re-enact a martial-arts movie from a gun-lover's perspective. Oh, and we also cleared out a Nephandi Labyrinth using a Marauder and Traditionalist lackeys and blowing up
all the things. No big deal, eh?
Moscow? We were sent in to investigate the theft at a local museum. We ended up nearly causing Armageddon. Actually scratch that, we
caused Armageddon and then promptly
un-caused it via the power of FRIENDSHIP and FORGIVENESS and GIANT STOMPY GOD-ROBOTS.
England? Werewolf car chases and caern assaults and Pentex-killing, oh my, plus a bunch of Rogue Council terrorists and Rose tearing a Paradox Spirit apart by
hand fang and need I go on?
So no, I don't think that a CTC loop would be a good idea given our general M.O. We aren't operators who operate operationally (in operations), we're the A-Team. We cause chaos, whether intentionally or unintentionally, and we
thrive on it too. Our strengths have historically been in our characters' mental, social, and physical adaptability to changing situations: we've been extremely good at re-purposing "useless" assets or turning enemies into kinda-sorta friends, and we've been very capable of coping with chaos and adapting one step ahead of our foes.
Our current biggest enemy, Threat Null? They don't have that same kind of adaptability; they
can't change like us. If we go to an alternate timeline where they're invading and Panopticon is the last Convention standing, we go to a chaotic warzone which plays to our strengths and to their weaknesses. Yes, they can overwhelm problems with sheer firepower, and at some point we'll presumably have to make a last desperate retreat, but that's the sort of fluid environment which presents us with a wide array of options for write-ins, improvisations, and general messing-around which lets us play effectively.
I'd also add that much like the various Exalted plothooks we've seen so far, the closed-curve hints could be handwaved with offscreen action, or with a separate write-in from EarthScorpion if he wants to, without sacrificing it entirely. Ditto for the other options, if we do choose the CTC loop. And though it's not exactly a primary consideration, I personally think we'd enjoy the more 'open' environment that an alternate universe would allow us, instead of the relatively linear and Paradox-fearing playstyle we'd have to do in the CTC option.
