DISCLAIMER: I completely forgot about the solstice event, therefore, the event will be one week later than it should, official solstice was 21/12/2016.
Let's game the shortest day of the year away. The event will officially kick off at 08:04 (Sunrise) and end at 15:54 (Sunset). Any game goes here, as it's a community gaming event.
The Solstice is officially at 10:44 Community Time.
