Quantic Dream founder David Cage and Thatgamecompany's Jenova Chen have independently spoken out against what they perceive to be the immaturity and narrow focus of modern games.

"The industry is too far balanced towards kids and teenagers. It's too focused on violence," said Cage.

"All I want to do is offer some diversity to the medium. I want to give people the chance to buy something other than ten different first person shooters and RPGs. There should be games for all ages, all tastes. Whatever is possible with interactive entertainment should be explored, and I don't think we're seeing that right now."

Chen had a similar message for the industry.

"My biggest complaint for computer games so far is they are not good enough for adults," he said.

"For adults to enjoy something, they need to have intellectual stimulation, something that's related to real life. Playing poker teaches you how to deceive people, and that's relevant to real life. A headshot with a sniper rifle is not relevant to real life. Games have to be relevant intellectually."

"I think Journey is more artistic because of the rawness of the game."

Both men recognised that most content was profit-driven, and that was reflected in the material tackled.

However, Cage questioned whether a wider focus would hurt studios which usually realised combat titles.

"Is [making shooters] really a safer bet? I'm not sure. Releasing yet another war-based shooter; there are already so many on the market, some of which are so incredibly popular. You probably run the risk of being crowded out in that genre."

"But it must be profitable for most people, because it's what the whole industry does. If I wanted to make just profit I'd have made Heavy Rain 2 and 3 and 4 and 5 for our publisher," he admitted.

Chen’s was also frustrated at the pricing of AAA titles.

"Right now, games are so expensive; they're $60. If they don't let you kill over a thousand people, the game is going to be dead within two hours. Then they have a problem justifying 60 dollar prices," he said.
