We don't know much about the game yet, but the turn structure, according to the hunters' sheets in the video, starts with dawn (daytime fight), day (only hunters' actions or travel), dusk (nighttime fight) and night (everyone's actions, hunter can't travel). While I dig this, there is one thing I'll miss from 2nd edition.
Right now, during the day, Dracula is desperate to avoid the hunters, and feeling the night approach is an element that adds a lot to the mood of the game. During the night, planning to get to Dracula at dawn is very common in my games. In 3rd edition, though, every turn is the same: if you arrive to Dracula's location (which you only can do during the day), you will fight him at night; and conversely, if Dracula attacks a hunter during the night, the fight will happen during daytime.
The house rule I thought about (hopefully) brings back a bit of that sensation. I would use seasons with different durations of day and night, so in summer all combats would happen in daytime and when winter arrives every fight would be done at nighttime. Spring and autumn would follow the standard rules. The proportion of turns among spring, summer, autumn and winter could be 3-2-3-2 (so 60% of the time would follow the normal rules).
Maybe some other wheather condition can substitute for the passing of seasons in a matter of days more realistically, but this is the gist of the idea. What do you think?
