Unfortunately the ambiguous nature of most of the game elements was really a double-edged sword. On the one hand, it really did create a certain sense of mystery and uncertainty in an unknown world. On the other, it frequently led to players having to break from the game experience to find answers online, and with that, eventually came the -expectation- that players would do that. I think the game would have been well served by a few more NPCs strewn here and there who offered those essential hints if players found them. When almost no one stumbles across the way to do those things organically, it creates the expectation that you shouldn't bother to ask other players... you should google it your **** self. But if 20% of players will stumble across the solution on their own, it may not exactly be a huge game-wide mystery, but it should at least be enough to create some atmosphere without making for a frustrated player base.
Ok, now we're going to get slash fiction of Wint x Kachi somehere... rule 34 and all...
Never confuse your inference as the listener for an implication of the speaker.
Good games are subjective like good food is subjective. You're not going to seriously tell me that there's not a psychological basis for why pizza is great and lutefisk is revolting. The thing about subjectivity is that, as subjects go, humans actually have a great deal in common.
