You aren't really meant to know where the in world the camper sequence is. It's taking place some time in the future. We can't really say where and how the world turned out because that hasn't been covered in Muse's lore. Also if you knew where, you'd possibly know what the true end is. Although you can draw some ideas based on the type of trees present, but given that so much time has passed, it really could be anywhere. We could maybe add a note of that. Maybe make up the name of a forest. But then we'd run into the same problem.
Not feeling much for William is intentional. He's not going to be the McGyver, do everything perfect the first time, kind of protagonist at this point in the story. Most Visual Novels tend to be created within the 13-18 age bracket. There is a lot of reasons for that. One of the most common is because the main consumers of VNs in Japan are those who did not have the best high school experiences. They want to go back and do things differently. Hence why you see the vast majority of them set in schools.
Because of this, emotions and personalities are a little more wild. The maturity level of characters can often be rather low. Although there always will be one character that is the mature straight laced character. There are also some real bad ones where the protagonist is about the biggest jerk you'd ever see and there is next to no way you'd ever feel anything for them.
Dust and Air actually hits in the 18-25 bracket. You see William now as more of a screw up before you see him later after maturing. So he is intentionally a bit of a screw up right now.
William's interest in the event is simply not there. At this stage in the story, he isn't all that interested in it. His interest is in exploring the city and seeing something he hasn't gotten a chance to see back in Mole. We can rework some lines a little, but really he's a crossroads character in the NA. Hasn't decided what he wants to do, or where he wants to go.
Day 2 is probably what you'd be more interested in as we explore more of the faction interactions. Unfortunately, it is still in development. You'd have to join us as a tester to see it and, right now, we haven't released the rest of the NA to our testers yet.
Personally I feel ya on the political world building side because I'd be interested in it as well. I'm a veteran player too. That's certainly something I'm interested in knowing. Just, as one of the writers, I know there's so much more coming. A lot of the answers you want will be addressed either in the NA or the story arcs.
There is also a danger is unloading all the political at once. Which is what Lucas did with Star Wars. Some fans loved it, most just utterly hated it.
If we were able to release all of this at once, I'm sure it would answer a lot of questions and ease a lot of emotions. Unfortunately if we did that, we wouldn't need to release the VN at all because you'd know the entire story. That wouldn't just be shooting ourselves in the foot, but dropping a nuke on it.
However, we will consider expanding the demo to include Day 2 in the future. Or perhaps chunks of Day 2. There's pros and cons to doing that. Just like there has been pros and cons to releasing just this Alpha Demo.
