I've been wondering lately whether there are any other fans out there in this forum of alternate world stories.
The most widely known in comics would be Earth 2(pre New 52), and maybe the Age of Apocalypse earth.
So...what are your favourites ?
This is a genre I have loved since Star Trek probably, combined with my adoration of Planet of the Apes, and then the discovery of DCs multiverse. I always grabbed the JLA/JSA crossover when available, (and wasnt there an issue with the Freedom Fighters from yet another Earth?) and many of my childhood favourites were JSA members. This also led me to an obsession with the All-Star Squadron for a few years in the '80s.
Personally I dont count the myriad "imaginary" stories, or "what if ?" type, but like the "canon" alter-worlds. So Days of Future Past is a particular favourite, but Superman Red/Blue isnt what I'm getting at for the purposes of this discussion.
I also really liked where the Ultimate Universe went up to the Ultimatum stuff. I enjoyed their slightly more realistic approach, and while there were some misses, in general I enjoyed the most of it.
