Paris games studio Quantic Dream will remain an exclusive Sony partner in the long term, according to the studio's co-CEO.
In an interview with Official PlayStation Magazine, Guillaume de Fondaumière said that it was the nature of the Sony partnership that has spurred the studio to remain an exclusive PlayStation developer.
"We proved with Heavy Rain that we can be profitable by making a game for just one platform. Would we have made more money by going multi-platform? Of course, but on the other hand, we wouldn't be working with Sony as a publisher," he said.
"This isn't a partnership where we are forced by a big company into giving immediate results. That's fantastic for a studio like us. Ever since we started our partnership, Sony just said it was going to give us the money to build these games and we said we were going to work as hard as we could and reward it for its trust.
"We're certainly not going to change partner for the sake of making more money; that's not the philosophy behind our studio. As long as we can create the games we want to create, we'll stay with Sony."
de Fondaumière explained that Sony signed a partnership with Quantic Dream in 2006 and had fully funded the Heavy Rain project. He said the game, which has sold more than 2 million copies since its release in February 2010, was "highly profitable".
A rush of awards for the game followed, from BAFTAs to Game of the Years, and de Fondaumière believes this could have created conflict with a publisher, had it not been Sony.
"There was this one thing about our partnership with Sony," he said.
"After the success of Heavy Rain we sort of knew they were going to ask us to make a Heavy Rain 2, and we said please understand we're not going to do that. We said we still believe we can do so much more with something else, and they accepted our idea."
