In a recent statement, Phil Harrison clearly expressed his feelings on multi-platform ports. Harrison says easy multi-platform ports are a thing of the past.
Sony’s Head of Worldwide Studios has said that the choice developers face when deciding what hardware formats to support is more difficult than before.
“Development and support for a format is very important yes, and the story is very different these days to how it was with older formats,” he stated. “In the past you could pay a million dollars for a PS2 game and get a $50,000 Xbox port thrown in. Those days are gone. Developers have to pick their formats much more carefully. This is partly because of the huge cost of development. But it’s not just a financial consideration. It’s about strategic marketing and the online consumer. It’s about how a game fits its format."
