This game was meant to be different though. Asking the wrong questions was meant to have a big impact, but you will always get the guy. Also, this game isn't open world like GTA and RDR...
I know a couple of people who have it, who are pretty disappointed. They say even if you ask the wrong questions, you will still get the same outcome, so there is no real story-branching. They say the solving part is pretty fun though, but it is very linear. No idea what you mean by Sandy?
