Personal thoughts about interactive books.
Unless multiple researched and well thought storylines are pre established, I would be bored to death. Having read tons of stuff, I often find repeated stories and patterns in what I now read. Well written scifi is normally devoid of "clichés"(french for snapshots, the accent on the e is inportant because otherwise it would mean diarrhea, but I guess it would be relevant to some stories
). This is the most important factor in my choosing scifi as entertainment.
An other factor that would steer me away is the fact that making a choice in the outcome would make my concentration in the story wander. Reading is like cinema inside my head. Once I get the feel of the author's wording and style, I get grabbed in the story and only emerge at the end or the next interruption. Having to stop to troubleshoot a story, for me, is more akin to work than entertainment.
But I would not be against trying it once...
