Train2Game students, particularly the QA Testers, will know of the importance of testing during a games development.

Now, in an interview with GameSpot, Valve has revealed that they believe playtesting to be the most important part of game development.

“For us, playtesting is the most important part of the game development process,” experimental psychologist and Valve’s playtesting lead Mike Ambinder told GameSpot.

“It’s not something we save for the end of the development, or use as a quality assessment or balancing tool. It is the dominant factor that shapes our decisions about what to release and when to release it.”

It’s a statement that Train2Game students who haven’t already been testing games throughout their development should really take on board.

Valve uses something called ‘bio-feedback metrics’ as part of the testing process. It features standard observed play sessions and surveys, but also involves tracking eye-movement with monitor-mounted cameras; monitoring heart rates; and even skin conductivity tests.

Valve use all of these to determine the players enjoyment of the game.

“We became interested in the use of biofeedback both as a playtesting methodology and as potential user input to gameplay because the idea of quantifying emotion or player sentiment seems to have utility,” said Ambinder.

“On the playtesting side, recording more objective measurements of player sentiment is always desired. People sometimes have a hard time explaining how they felt about various things, and memories of feelings and events can become conflated.

“Conversely, if you have a more objective measurement of arousal or engagement, you can get a clearer picture for how people are emotionally consuming your game.”

Last week, the Train2Game blog reported that Valve’s Steam service is ‘essential’ for indie developers.

So Train2Game, how important do you believe playtesting is to the game development process? How would you go about it?
