Star Wars Tales ran a total of twenty-four issues. The first twenty were simply meant to showcase fun little stories -- they didn't have to conform with established continuity and often didn't. Starting with issue twenty-one, however, a new editor came on board and the series became a mere extension of the other Star Wars comic series running at the time -- a dumping ground, if you will -- with stories that, by-and-large, were meant to fit into pre-existing canon.
Now, this makes me wonder -- is the cancellation of the series so soon after the regime change a coincidence, or did the powers-that-be's unhealthy preoccupation with "canon" end up alienating the readers who liked the comic for what it was, not what they wanted it to be?
