How connected is the DC Universe compared to the Marvel Universe?
I'm asking straight to the point about modern DC:
Just how connected is it compared to Marvel?
I've always been Marvel over DC, but that doesn't mean I can't enjoy DC. I thought I'd ask about this, considering that to me, one of the biggest draws for Marvel is the shared universe.
One of the things I've always liked about Marvel is just how connected everything felt, where heroes meet and possibly team up with each other on the regular while going about their own lives, fight villains normally associated with someone else while still having their own rogues, have supporting casts migrate between different characters (such as Iron Man getting key Spider-Man character Mary Jane Watson as a PA for Stark Industries), and that many worldbuilding elements are present throughout all the books. Events that happened somewhere else can be relevant to a different story, and it's common for books to reference each other (often with captions to tell you where to look).
Just how much of this is true for DC?
I've been told in the past that modern DC is super connected, and isn't nearly as walled-off from each other as I think it is. I've long held the belief that DC is a bunch of small settings making up one large setting, and that Marvel is one large setting making up a bunch of smaller settings. What do you think overall? What are the best examples of the shared universe connection in DC, and how does it compare to Marvel?
Please, by all means, educate me on this.
Thank you.
