For those who've been following the discussion thread at GSC, Frozen Sky is still being developed, albeit slowly. This started out as (and has always been) more of a personal project, as I've never been happy with the other "winter" mods that have been available. At my current rate, I still intend to release Frozen Sky in two parts - the first being the visual/aesthetic aspects, the second being the gameplay changes (plus the visual). Over the next few weeks I intend to add a couple more demonstration videos - one showcasing the changes to the dynamic weather system (and the revised day/night cycle to coincide with real-world winter day/night cycles), and another showing the first few minutes of a new game with gameplay changes in place.
