Sega has at last provided specific details on how the Wii Weather Channel will affect Wii revival of the Nights franchise.
Nights Hoshifuru Yo no Monogatari will connect to the channel, which offers pseudo realtime weather updates for your area of play. The real world weather will be reflected in the game's My Dream section, where you interact with the artificial intelligence driven "a-life" creatures.
Screenshots show the My Dream sandbox environment under clear skies, under clouds, being snowed on, and with lighting in the distance.
The a-life creatures change their behavior based off the time of day, season, and weather, so this little bit of reality could be a big deal.
