I honestly don’t expect them to be continuations of the same game, not the most successful entries, that is. I expect the realization that the short story doesn’t always translate to a novel to be a reoccurring one. I suspect that, while they may both contain the same seed, and may recycle some code and concepts, quite a few authors may take the overall idea from the Speed-IF and reframe it properly for a larger piece.
Then again, maybe someone will subvert my expectations and will find a successful way to work with what they already have, maybe an anthology approach like Ray Bradbury’s Martian Chronicles. That’s the point, though, figuring out how best to approach those two disparate problems.
