The NASA education and outreach budget is $170 million with the sole purpose of generating interest in NASA. It's basically a slush fund to "bribe" voters with "wow worthy" materials, like APOD etc. If they spent even 2% of that on ED, and they put a NASA stamp on Elite Dangerous, then the amount of Press coverage for ED would probably generate more public viewership and excitement than every successful NASA mission in the last 10 years.
As for the education portion. I have a degree in Astrophysics, and I still think I have developed a much better working understanding of general geography of the Milky Way through ED than in my entire time at university. This kind of hands on approach to mapping the galaxy isn't really taught in schools at the moment. And even though you get the general idea from books, 2D charts, and planetarium software. There is something altogether different about having to use that information to survive in a 3D living galaxy. It's like the difference between reading a dry DVR instruction manual, and actually working with the device to figure out how to set the clock to local time. You don't really *know* something, until you have to use it.
Interestingly, most professional astronomers have a much weaker grasp of where things are in the sky than amateur astronomers, and this is because professional astronomers tend to focus their entire study on one type of object, or even just ONE object. And they find them by using highly sophisticated mapping software that just requires 2 precise coordinates. But amateurs use much coarser gear and actually need to use the naked sky itself to initially align their instruments, and though their studies are not nearly as indepth or sensitive, they range every part of sky and every distance visible with a "small" telescope. I think that this disparity in general knowledge actually hurts professional astronomers, because they might be missing a more global view of what is going on, and given that the size of their subject matter is largest object ever known (aka the Universe), this is a potentially hobbling disability.
I honestly think that ED should be required homework for every Astrophysics and Phyiscs undergrad. And that this would do quite a bit to advance the field of astronomy in ways that we can't yet imagine by allowing the more rigorous studies to be shaped by an intimate and intuitive knowledge of the cosmos.
