VT theory: What happened to the 1st dimension (Earth)?

The 1st dimension is the home world of humans, where people have jobs and normal homes, but... the thing is there are rarely any actual humans... here is my theory why.

TOWNS & CITIES

Yes, there are some citizens in the towns and cities, but sometimes, it's abandoned, no sight of humans, except for probably the characters visiting the place. Example: When Sally and (Her father?) visited Amityville, the father said "Hmm...where did everyone go, its like they just all left." All of the buildings are either haunted or just abandoned.

What about Hell's Island?

Well, from the gravestones I think everyone has died since the 70's from the "Disease". The disease left no survivors at all, the whole entire town was wiped out except for a pretend sole survivor who was really Cardboard Friend.

TECHNOLOGY

The technology is actually outdated, not by extreme, but a little bit. A lot of things come from early 2000's or the 90's.

CIVILIZATION

Everyone seems to be strange...traumatized strange. The humans try to fight off the creatures as much as possible. However, PIE is seemed to be the most popular job in the 1st dimension. Everyone seems to live in ruined houses or alone on islands, unlike the Acachalla's.

THE "Secret" WAR

We've seen quite a few videos about it, but after the war no one seems to talk about it. It's very very silent, not even war-fascinated Papa Acachalla talks about it, the war where it had the mech, the zombie invasion, and where Jonathan Logan's body was found, the world looked like a mess, cities were destroyed, creatures were everywhere, also Papa used the code name "Scott" in the war, that's the only thing he has said about the war. No one else has any comments on the secret war.

CONCLUSION

I think Gmod VT is post-apocalyptic, the secret war was 1st dimension vs 13th dimension vs Combine, which killed a lot of people, hopefully more things about the secret war come out on VT. (Which is sadly unlikely :(...)

BYE!
