1. A method for customizing a recorded real time simulation based on simulation metadata, the method comprising: recording data corresponding to an execution of a real time simulation on a real time simulator, the recorded data being organized according to an original simulation timeline, the recorded data comprising: at least one action performed by a user interacting with the real time simulation, at least one event occurring during the real time simulation and at least one variation of a parameter during the real time simulation; and processing by a processing unit of a computing device the recorded data to automatically generate customized simulation data based on the simulation metadata, the customized simulation data comprising at least some of the recorded data and being organized according to an updated simulation timeline, the updated simulation timeline being generated based on the original simulation timeline.
