I've just been "playing" Steve Jackson's Starship Traveller or as much as you can play these things without dice to hand. I'll come back to these books later this summer because I think (although it's a gut instinct not a rational thing) that these books are much more important to science fiction than we have realised.
Just playing this book through once I was struck by how almost all encounters turned away from people and towards objects, and this is even with a set of decisions which always chose people rather than place (I suspect boys at the time played it differently).
It's as if, stripped of the camoflage of true story, this book has slid along the spectrum to the very extreme of sf-non-involvement with the human.
Must muse some more.
