I wonder if 30 minutes is a bit fast for those of us who might want to farm certain creatures, but I suppose we can just fast forward in a similar way to that in Elder Scrolls to ensure we're always prowling at a certain phase of the day.

I really like day/night cycles in games. If more than the lighting will change, even better. personally I'd love it if certain towns would be more active at certain points of the day, sort of like rush hour or something.
