Ludum Dare is a 48 and 72 hour game making competition globally hosted over the internet; Ludum Dare 30 ran from August 22nd to August 25, 2014, with the theme "Connected Worlds".
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.
