Outlanders would exist regardless of Deathlands.

See, there's a solid mythology for Outlanders and an actual progression of plot, rather than the same recurring dream over and over again.

Doc Tanner wakes up and asks his wife for a Brandy, that's a good thing.  It means he woke up in the universe where Kane didn't act like a mental erectile dysfunction (Cawdor) and prevented the megacull of humanity.  The next jump always promises to be a good one, and if it's waking up in a casement where a hero, not a one-eyed sociopath, had a choice about the destiny of the multiverse, then hey, waking up with a rumbly tummy after a nightmare is a fine end for the series.
