DC events always brought the gang back together

My favourite part in almost all of the DC crossovers of the 80s and 90s (there wasn't one in Legends, interestingly), was always the bit where everyone gathers in a big room or space somewhere, and you get a snapshot of what's hot and what's not in the DC universe at the time. 

Look, there's the six month period when people were supposed to give a shit about Damage; and there's the Justice League International at the time. See when they try and make the Forever People a thing again. Look at how the artist who does the worst job - reducing figures to scratchy outlines because there is a really rad computer screen he wants to show off - becomes the biggest artist in comics for a while.

The big guns are always there, but there are still changes in costume and style. These times never last as heroes change and evolve, but they'll always have those times there was a Crisis to deal with.
