I just wonder what the thought process is behind that. To distinguish a couple dozen scripts from each other, I'd think it would be helpful for them to be on as wide a variety of topics as possible. Space opera, sf/f in historical settings, sf/f comedy, shows about genetic engineering, shows about intelligent robots, shows about dystopian future police states, time travel, virtual reality, anthology series, just go hog wild.
If you're just flailing wildly, why not try everything out? Maybe there's somebody out there who's actually capable of coming up with a workable time travel TV series. If Syfy is experimenting with a TV-video game crossover, why not do your own experiment?
