Well the running issue here is that throughout the Secret Wars event they hardly disclosed the reality designations for the different domains. I can understand why: If they spent the entire story classifying which character came from what universe, it would have bogged down a lot of the stories which -- for all intents and purposes -- were mostly one-off tales that were fun little romps, but ultimately don't have that much impact on the entire event.

The expectation for us here at the Wiki is that the All-New All-Different Marvel Handbook that is coming out in ... March?... It's promising an entire entry on Doom's Battleworld that hopefully will answer all those technical questions.

Until then our editorial policy was such that we would keep the Secret Wars stuff separate (unless the character designations were obvious, like with the 616 & 1610 characters who were involved in the main story and Ultimate End) because although they revived all these familiar alternate realities, they took a lot of liberties in what plot elements or characters they used. Since Marvel is somewhat notorious for creating alternate versions of alternate realities (for example there are many versions of Days of Future Past, 2099, the Squadron Supreme Earth etc.) we can't assume that the "familiar" territories are the from the same exact realities that we are all familiar with.
