Female focus testers are a rare thing in the games industry, Naughty Dog has revealed.
“Another aspect that influences how a game is promoted is focus-testing – players are rounded up and are asked to view materials and answer some quantitative and qualitative questions about it," he said.
"My big surprise during this process is that the research group wasn't planning on focus-testing female gamers – it's something we had to specifically request.
“I hope this is a relic of the past that will soon go away."
That same firm also recommended that AI companion Ellie be moved to the back of the box art – something Naughty Dog ignored.
The Last of Us is due out on June 14 for PlayStation 3.
