Joystiq reports on the GDC announcement of PhyreEngine, a new free
cross-platform game engine from Sony (thanks Mike Martinez). More details are expected
today, but for now they point out this development environment powers the recent
releases of flOw, GripShift, and DiRT, demonstrating it can create games for PC
and Xbox 360, as well as PS3. They point out an obvious motive for Sony to
support cross-platform development, in that using PhyreEngine will guarantee PS3
versions of games that are least the equal of their counterparts on other
platforms.
