At least one game company boss believes that free-to-pay is not just a business model within the games industry – it's the entire future of gaming business.

Machine Zone CEO Gabriel Leydon, whose company found success with mobile titles such as iMob and Global War, believes that traditional pay titles were on the way out, to be replaced by a free-to-play or even a get-paid-to-pay model.

According to Leydon, these such models will be the only way to make money in the industry.

“There's a lot of backlash against free-to-play, especially from the traditional game industry, because they don't understand it. They feel like free-to-play is somehow tricking consumers or some people are spending too much money.

"The way I look at it is the console industry is actually the abusive industry, [that] treats its customers like they're their enemy,” he said.

He believed the video-game industry should be encouraging used sales and returns.

“They should be encouraging refunds. But they're so locked into this model of selling people sequels year after year after year that they feel like, ‘Well, if the player doesn't like it, that's their problem’."

Leydon saw the quality gap between pay and free-to-play diminishing.

“The quality is also ratcheting up pretty fast on the free-to-play with games like League Of Legends and now CryEngine is being used for free-to-play. There's no room for a paid upfront game anymore.”

The current models wouldn’t be around for much longer, he said.

“I think you'll play games that you'll never pay for. I think you're going to be playing games where the game pays you to play… I think we're going negative. I think we're going below zero in the future.”
