So far questions that have been asked:
What are most people's attitude towards supers?
A lot like the X-men movies, people are wary or even outright intimidated by what superpowered individuals are capable of. Concerns over such things as human rights have over the last few decades gone over incredibly smoothly (even LGBT issues were nearly so easily pushed through that it seemed more of a nod to protocol than anything else). But instead of LGBT or "war on terror" issues being the mainstream concerns, the world is fighting for and against xenophobia.
On one hand some believe that Earth should belong to Humanity, condemning the Mutant populations around the world as well as rejecting any refugees or citizenry to other intelligent species. The debates have been long over the last 30 years, and in rare cases bloody.
On the other hand, there are many who adopt a "live and let live" outlook, and also others who believe that Earth should be the home of humanity, but a refuge for any who want to call it home. To date, there have been only a handful of non-human grants of citizenry, and none of them were given to a biological non-human. In short; It's easier (not by much) to be a robot than an alien in this world. The 3 Instances of non-human citizenry so far are Barricade, Titan (Later revoked when he turned to extreme violence), and an Android named Jim who has since become a doctor.
What year is it?
2010
Does this year reflect the way life was at the time?
Technologucally things are nearly the same. The only difference is that computers are nearly twice as capable as we know them now in regards to processing, memory, and storage. Furthermore there is a quickly developing industry (which is still a minority for now) which is developing methods for synthetic fuels that are not only renewable but more effecient than current gasoline and other liquid fuels. That said, financially speaking things are a significantly more stable in the first world.
If it's futuristic, how far? Are there flying cars? Space travel?
No flying cars, public transit teleporters, or replicators. Space travel is far more prevalent though as NASA was scooped up by private industries and there are now 3 orbiting space colonies around earth for scientific research. Interplanetary travel is advertized as "just a step away". Scientists cite that the major limiting factor is the sheer amount of travel time needed between planets.
What are the world governments like?
Generally speaking the worst it seems to be is fierce rivalries. The USA and Britain are still as passive aggressive as ever. I feel cheap saying it this way but... Imagine NOW. Just minus North Korea being a twatnugget and the whole "War on terror" BS never existing past having gotten Bin Laden. And even having captured Bin Laden would have happened much sooner with the existence of super powered folks also hunting him down. Safe to say that the isse was dealt with, and Al quida itself dismantled (for all intents and purposes) within a couple years, and it was this point that lead to the formation of S.H.I.E.L.D.
How did confronting Al Quesadilla lead to the formation of S.H.I.E.L.D.?
After all the big boys in governmental leadership realized that they have too much stuff to sort out just between the different regions of the planet Earth, they opted to create an international police force and government that would have a very focused goal; Ensuring the safety of all residents of Earth. There were of course a few who still are adamantly uncooperative with S.H.I.E.L.D. under the pretense of not wishing to give one authority too much power. An issue which is officially addressed by governments around the world making sure their authority is not overstepped. To date S.H.I.E.L.D. has not had to force any major police actions against an established government.
Is there a goal to the game, aside from just RPing?
Just RP'ing and telling interesting stories about interesting characters. Really just have a field day. There might come a point where I pull an "Avengers" bit and throw some big bad bastard at folks and a bunch of ya have to team up?
