Okay, I know I'm late to the discussion, and thankfully the conversation seems to be going in this direction anyway, but I think I'll try and give it a further nudge.
I said this in the build-up to the Marvel RPG relaunch, and I'll say it again here: there is nothing that's better guaranteed to suck the life out of any excitement for a fresh start than endless bickering over what continuity period to pin it down into. It's overthinking to the point of being neurotic. "Oh, we could have our continuity match up to post-Brightest Day, pre-Flashpoint, and if posters make sure to have Wikipedia open in one tab and ComicVine on another while writing their posts, then they'll be able to make sure their posts remain in canon, and they make sure that their characters actions don't contradict that comic from June 2011, and AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAARGGGGGHHH!"
Here's the problem with making a continuity cut-off point. It hurt the Marvel RPG. And in recent years, it's also hurt the DC RPG. Stories often become about, "Let's redo what the comics did, so we can catch up and match things up to what they're doing." And storylines that are simply an exercise in getting from continuity point A to B rather than being about having fun and being creative inevitably flounder.
When the Marvel and DC RPGs first launched, it was simple. We started the continuity with what the continuity was in the comics at that particular moment in time. And by this, I don't mean that the DC RPG had a "post-Rebirth continuity", because batnkevlar skipped to the end of Rebirth and made an educated guess that Hal Jordan would be Green Lantern again when he chose to play as him. What I mean is that we DIDN'T OVERTHINK IT. We picked our characters, and portrayed them as if everything that had happened to them in the comics happened, but we were starting with enough of a degree of seperation that we could just do our own thing.
For example, if I pick Batman, of course the origin with his parents being murdered stays in place. He can refer to having his back broken by Bane or travelling through time after being hit by the Omega Sanction as stuff that happened to him once, but that doesn't mean I need to have him travelling the world spreading the franchise of Batman Inc because that's what the comics are doing in current continuity. I might want to mention Batman Inc as something Batman did, another player might want to play as Man O Bats, but we don't have to be beholden to the war with Leviathan because comics continuity tells us that's where we are in history. That's overthinking it. Everything that happened, happened, but now we're telling new stories.
With someone like Superman it may be more complicated, as his history has been changed by the reboot. But it's not like you have to retell his origin story. Okay, Ma Kent is dead and he's not married to Lois. But he's still Clark Kent who works at the Daily Planet. He's still Superman. The basics are there, in place, for you to launch into portraying him and having him punch bad guys. Don't be neurotic about it. Just pick him and play.
This is a new chapter, a clean slate. Let's not think about what we're doing in relation to DC Comics history, but in relation to our history. We are just doing the same thing that we did 7 years ago: taking the current comics of the time the game starts as a basic launching point, and from there doing totally our own thing and creating our own stories, not being beholden to the current storylines or continuity of the comics. It's not complicated, unless we make it complicated.
