Really liking that vid!
I did and I didn't find it difficult to make the criteria in that it's so geared towards being an alternate Earth and obeying the same laws of Physics that really anything that's fictionalised to some extent will fit. My own story will get published whatever and I was close to completion when I decided that it could qualify in this competition more or less even though there's little of the fantasy or sci-fi element in the theme (some myth and folklore aspects). It deals with social and cultural elements and emotional health post-war/violent trauma with a 'names changed to protect the innocent' approach to fictionalise actual conflicts in West and Central African locations (Biafra for real and the Rwanda genocide reworked) and the only true alternative element is in featuring a Utopian community solution under the auspices of a UN style project with fictional aid/relief organisations woven into efforts that are actually being attempted in the real world.
I think for this compy they did revise the criteria slightly and certainly the novel size (I think it was between 70 - 120K previously) so that the parameters of the science side of things was more proscribed so that people were having to write not too far from reality, which has some merit in that, if you can't write coherently about things that actually are (or could easily be) how can you write about things that really aren't? Even fantasy has to have some rules I guess but how that's interpreted for this contest may be open to argument as to how far you can roam around reality and I know I haven't departed too far from that line to the extent that maybe I don't truly meet the criteria that well or at all.
As for future projects - I'm working on a more classic fantasy series that has some sci-fi origins (it's got some nods to Darkover, Earthsea and Dune/Arrakis) but concerns an archaic but high-functioning civilisation and some supernatural aspects
I'm not writing too much for it yet but I have been having some fun mapping the world it all happens on so once this month is over and I know what, if any, success I've had with the finished novel I'll be working on the new stuff more or less full time
