The third dimension focuses upon the internal representational world – or diegesis – of the game
or simulation, which in this context is used to mean: the mode of presentation, the interactivity,
the levels of immersion and fidelity used in the game or simulation. This dimension is particularly
significant for the framework as it highlights the difference between being immersed within the
game and the process of critical reflection that takes place outside the game. These distinctive
spaces inside and outside of the game are broadly metaphorical of course, but serve as a method
for supporting the teaching aims and learner objectives by defining the ‘learning activity as play’
and highlighting the potential of briefing/debriefing which take place before and after ‘serious
play’ to reinforce the learning outcomes. This dimension also allows us to focus some analysis
upon the format and mode of the game or simulation, which is particularly important from specific
‘games research’ perspectives.
