It's been a long time since I've read that one, but, from what I remember of it, the VR and time travel used were similar enough to things that had been done in the SG-verse that they didn't hit me in the "cool, SF!" way. Maybe that's key to what I'm talking about, and what I'm looking for--SF tropes that haven't been done much on SG, already, to the degree that we come to expect them, both in the show and in the stories. Because it is a SF-based show, and does have a lot of SF elements; the stories I mention have SF elements I've seen before, but maybe not so much on SG eps--I think the ones I remember from reading SF novels are probably the ones that ping me, the most. (It is a good story, though waaaay too long for me to re-read before responding to you in a timely manner. *g* I will re-read it over the weekend, though; thanks for reminding me of it.)
