There's no reason for all of Pacifica to be completely abandoned and in a state of decay. Part of it near the river could be doing okay, but further south and to the coast, where the failed investments happened, that's where there'd be a lot of desolation.Yes and Las Vegas expanded quite a bit over 60ish years. Whereas Pacifica was never finished but abandoned. Also the welcome sign faces a downtown metropolis, not a desert which means logically it would have been placed somewhere near the boarder between the two.
Something like this:
Though looking at it now, I noticed my Pacifica is a bit too small, at least compared to City Center. I adjusted it to the size of the buildings there. This ain't the final version, don't worry
I think the tallest skyscrapers that we could see in Deep Dive were in the red circle. The position of V overlooking the OASC is probably somewhere near the green dot. The pier to the left of the red circle could be the pier the rollercoaster is on. Whatdya think?
