Chewy, I don't know if you are referring to me when you talked about posters with grandiose plans for the future.... if that is the case, allow me to correct your assumption.
It's true that I and TTT are writing a story set in the future of Vanguard, but that is it... just a STORY. An Elseworld story, as anything set in the future should be. That's what interest me now... telling stories, with a beginning, a middle section and a conclusion. That's the main reason, aside immediate circumstances, that had me retiring Euro and starting a new series, where the focus is not over characters, but over the story.
I had never grandiose plans for the future of the collective written Vanguard, at last since the third of fourth month after we started this thing. I have had always a preference for creating a team of superheroes, because I would be interested into seeing these metahumans delving with great scale tragedies... not aliens or marine monsters, but terrorism, media-manipulators, famine, war.
Due to the different cultural backgrounds, probably that would be impossible... and recently I embraced TTT's vision of Vanguard as adventurers... exactly what you suggests as your preferred setting for the "new" Vanguard. Our last story, imperfect or plainly bad as it was, was aiming right in that direction. I must add that today, I see much difficult over that kind of "flavour" for our team, as it, again, would bring the accent over the story instead of the soap, and I don't think it's what our group of posters is being equipped (and interested) for.
Mxy's idea, anyway it is implemented (with or without UN founds and backing, with or without Strikeforce roots) makes the continuity impact minimum (a group of people over a satellite or the moon or a secret base just interacts among themselves) and allows for a lot of big fights with just a minimum of story needs. Vanguard could be affiliated to Nato, for example, to cut the ties for any previously established continuity with UN, or be privately founded or they could found their own Paragon. I think an association with a body of governments simplify the need for clearance for flights, interaction with police forces and or military ones and such, but they are really just details and matters just if we give them importance, else we don't even have to care.
I must also point out that the experiment of the Strikeforce, although very short lived, of allowing the creation and use of many characters for each poster, it's not as stupid or bad or heretical as it could sound. Having many characters makes them a lot less central to the Universe, and brings attention over the story instead of the soap opera, keeping continuity to build up much slower.
