Elements of the free-to-play sales model may appear in all of Ubisoft’s future games, says its worldwide director of online Stéphanie Perotti.

During an investor conference call today, Perotti outlined the influence of free-to-play, citing its reach and profitability as reasons to integrate it into future titles.

“Free-to-play is a very flexible business model – the player has the capability to spend more than in a traditional model,” she said.

“The Settlers Online is set to make more money in four years than the Settlers brand did on PC over nine years.”

Free-to-play would feature heavily on next-gen consoles, but perhaps in tandem with full price games, said Ubisoft CFO Alain Martinez.

“There will be free-to-play on consoles, but in the future with games like Watch Dogs, we could see more opportunity for [full-price] games to learn from the free-to-play model.

“The next generation will offer more and more item-based content,” he said.

“This will benefit our games’ profitability.”

Ubisoft said it expected to earn €50 to €60 million (AU$61 to $86 million) from free-to-play and casual games in fiscal 2013, up from €20 million (AU$24m) in 2012.
