The original iteration of New Avernus has the world ending all the time. Ruin cards were drawn every turn, and did small things to you or, at times, did horrid things to you. The Meteor didn't show up at the end, it came as just one of many destructive forces. Asher thought that was a bit much, so now we have a meteor that comes at the end of the game. 

But the old Ruin cards aren't completely out of my mind...
So, what are you favorite apocalypses? Zombies? Nukes? Or is the good old meteor the way you'd like your fictional cities to end?
