Yeah it's a pretty fun thing to think about. That if you placed a bunch of heroes and villains together that they'd eventually all just hang out and becomes buddies and the bad guys would reform.
I've always found how Venom's origin was tweaked in animation's kinda funny. I remember one day just kinda thinking of the two and realizing how different they were. Like an executive looked at Venom's origin and decided "Fuck it, let's give an abridged version" and it became canon for the media interpretations thereafter.
Le sigh. Maybe if I bug Marvel enough. It annoys me the most because they have that whole Genext thing going on in Marvel right now sporadically making up new characters when they could've just continued this instead.
