Games that typically contain a large world that you are free to explore in any order you like. Completing objects may open up new areas or change how previous areas functioned.

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.
