@awnlee jawkingSince asteroid stores are so popular widespread, they're a bit overdone. As a result, I prefer the more unusual, non-standard ones, rather than the same-old, same-old.
Anyone can take it either way, yet โฆ the premise isn't very challenging or inspiring.
That said, a decent alternative would be using the same scenario, where the asteroid doesn't hit, so everyone remaining has to cope with what they all did in preparation for their last days on Earth.
Now that's an intriguing idea, simply because it hasn't been as widely used. I'm thinking of one I saw a recent rewrite of, where they build a deep underground tunnel where everyone holed up in, expecting everything on the surface to be obliterated, then run into troubles coping with each other, waiting for the end to come. Their deep tunnel refuse become their own version of pergatory.
