I love vintage sets. I prefer the old town layouts I grew up with. So while I have nothing against modulars, when I build my city layout, it will be in the 80's 90's style. I know that most people will not like it. But its for me.
I have learned that when I say I prefer vintage to modulars, no one really cares, in fact I've seen people get upset so I don't bother to post on the subject and I think that just snowballs.
I don't collect minfigs or starwars either. So I have a hard time finding like minded people. So I'm happy for you guys, it must be nice to have so many people to talk to about your cities.
I think you hit the nail on the head here. My generation (mid 30's) are mostly busy with careers and kids. I think we will see a large resurgence of the 90s stuff after older millenials retire. I remember being online back in the early 2000s and the focus was very different. Most lego fans I find in real life are much younger than I and not interested in the same things.
