ZaratanCho: So far the story and lore is told by scrolls and books you find as well as by the environment, so it is more trying to peace together things and a mistery. There is still a lot to come there, there is no dialogue yet but it will come(soon i think). I wouldn't expect lots of dialogue even when it is finished though. Having many human characters and such doesn't make sense considering where events take place and the story/lore.
I also only play games if they have a good story and dialogues but have enjoyed Exanima immensely. ;d I am really liking the lore and the story the carefully designed levels tell(there are some npcs already who also play into the story in a way). ;d
Non verbal storytelling works well (Bioshock comes to mind) so might give this a try.
