That post made me think about a thing.
Maybe conversations will feel very one-way since we surely won't have a voiced-character and conversations will have no hud (because of real time), therefore we won't have any choice to make while speaking to someone. So it'll be : press a key to start conversation, NPC talks alone. NPC stops talking. Press a key to make him talk alone more. So, yeah, I wonder how choices will be implemented and hope it won't make all the "dialogues" (well, probably monologues, really) flat and detached.
