Hey folks! Made-up word time! Canonicity!
So. EVE True Stories has introduced alts as an actual fluff mechanic in EVE, using a mechanism comparable to jump clones. The idea, it appears, is that while the neural element of various clones must be compatible, the physical form isn't fixed and so players/pilots may jump between different-looking bodies as they like.
Without getting into the ugly story mess of the Broker and impersonating whomever, however, it seems fairly reasonable that cosmetic changes between different bodies are viable without much expense, though presumably creation of a false identity would require some handwavium, explanation of SP differences (or quietly ignoring those as game mechanics that are hard to explain), and wanton bribery of CONCORD.
Alternatively, we could assume that this occupies a space comparable to the Star Wars Extended Universe, which is semi-canon -- whereas the movies are canon, novelizations of the movies are canon, and the mass of books are canon where they don't directly contradict what we know from the canon of the movies.
Thoughts?
