Apologies for the direct question worded poorly, but in terms of gameplay, what is expected to be meaningful?
(is the game a kinetic novel or a branching narrative? are interactions going to be measured? is there going to be failure status/events? etc.)
Anyway, i find impressive the amount of characterization that has been done with such a quite large cast and that each character feels unique enough .
(though, that should have been expected from a good story driven narative as this one seems to be.)
Also, what's the point of choosing who to talk with if the game will anyway think you did all of the possible interactions?
