I would also point out that 'A Seperate Reality' reprints a key phase of Doctor Strange's life as it deals with the passing of The Ancient One and his mantle of Sorceror Supreme passing to Strange, replacing the long-running 'Master of the Mystic Arts' title. There's also the first appearance of one of Strange's most interesting foes - The Silver Dagger.
It might be suggested that this era of Doctor Strange would be a tad too dry and dense for a modern readership, Steve Englehart's Strange was a far cry from the more flippant and relaxed man we have today. But if you like a solid and dense read in a title then 'A Seperate' Reality' is true value for money I say. They really don't make them like this anymore...
You've made me want to reread it, I have the 2002/3 release, but I note that my copy is missing from the shelf... hmm.
Those are the exact two stories I was meant, and your write... it is way past time for a reread.
