To tag up on what's been said: we're all starting off on the first week of, more or less, superherodom. Superman appears ([i]when I finally have him appear, sorry about the wait[/i]) and it sets off a chain reaction of other vigilantes and powered heroes showing up in this world, leading to things like mutants being more outwardly active and villains on an Earth-level coming out of the woodwork. The implication there is that every hero character is very green and amateur at what they do, leading to them being susceptible to mistakes and power levels that are far below their peak. 

So when we say that we don't want major threats like Darkseid, Thanos, Galactus and the lot beaming down from space and challenging the current crop of characters, we literally just don't want our characters either getting an automatic power boost to compete with villains on that level or, more realistically, getting killed. It's not interesting to have characters this new to the cape life be decimated by threats that are ordinarily saved for fully stacked teams and heroes that are more experienced compared to having them struggle against jobbers like The Rhino or Clayface. That's the goal, which is to build heroes to eventually [i]become[/i] capable of taking on bigger threats.

So no, we're not literally talking about the idea that the Green Lantern Corps just started and recruited Hal and Sinestro this week. That'd be absurd. Darkseid is obviously around and ruling Apokolips, he didn't just ascend to that throne. Galactus is out there. Thanos might already be off Titan, we don't know. It's just that for the sake of our player characters, the characters that matter to this game, it's the first week. Just don't throw something like that at any of them. We're telling a story as a group and that story is "Superhero? What even [i]is[/i] a superhero?" in a generalized sense.

[S]Meanwhile I'm over here playing two different characters who have been around for over a century. I did not understand the assignment.[/s]
