Does every fantasy story need to be about saving the world from some great evil? Can't it be about some guy/girl trying to survive in a hostile town throughout the years? Now I haven't played the game (mixed reviews and obscene price tag) so I don't know how they handle it, but the premise itself certainly has potential. I understand it can seem a bit disjointed if you're not working towards something overall but doesn't mean it can't work right?
Besides, western RPG world-threatening horrors are nearly always really, really boring. If where they succeed is the dialogue, characters and execution then is there anything wrong with putting the focus on that?
Not sure where I'm going with this, looks like I've just wasted your time. Sucker.
