Ludum Dare is a 48 and 72 hour game making competition globally hosted over the internet; Ludum Dare 37 ran from December 9th to December 11th, 2016, with the theme "One Room".
A turn-based game mechanic is the opposite of a real-time game mechanic. In a Turn-By-Turn mechanic (synonym), each player has to wait for the other to have played, so that they can play, and so on. This way, each player has the time to think about their strategy. TBT games rely less on action than real-time games.
