Dark and Demon's Souls both actually have fantastic stories and characters. It just doesn't tell you what is going on, they give you very small details from time to time through character conversations. Item descriptions then fill in the rest of the holes.
You manually you have to piece everything together after the information is given to you however. Basically, nothing is outright told to you. You have to 'research' the story. If that makes sense. I mean, even if you don't research anything, or put anything together in the game, you still can sort of tell what happened, well, actually it's pretty obvious what the moral of the story is.
Stuff like character backround, demon backrounds, how stuff came to be, all the details basically, you do it yourself by putting it all together.
