I've watched some non-spoiler reviews. Though one of them described how the 'connecting people' aspect worked in general with a few examples (but avoiding the more impressive/spoilery examples) and that part really has me intrigued.
The other review, along with Digital Foundry's tech review, described how traversal works. Also with a limited amount of examples. And this is the part I'm not sure if I'll like until I try it.
It sounds like it could be very interesting, and something I may like. But if I end up not liking it, then it could become a tedious thing I have to do 99% of the game.
