According to M2, "...the final count for layoffs since the economic meltdown in late 2008 reached 11,488 worldwide, with the majority of the losses coming in 2009." Apparently, most of the layoffs from the 95 reviewed studios are felt at the ground level. That makes quality assurance staffers often the first ones out the door.
Studio closings like Pandemic, Grin, and 3D Realms have been all-too-common occurrences in the past year or so but studios don't have to be closed to feel the impact. We reported the most recent spat of such layoffs earlier today in which Warner Bros. Interactive let go employees from its studios Monolith, Snowblind, and Surreal.
However, average game development costs tell a much different story. Amidst the industry-wide whirlwinds of downsizing, restructuring, and layoffs many studios are spending more on development than ever before. M2 Research also reports (via Develop) that games developed for a single platform cost an average of $10 million. That said, the average cost of a multiplatform "nex-gen" game is currently reported to be around $18-$28 million.
Of course, there are almost always exceptions to the rule. Infinity Ward's Modern Warfare 2 is rumored to have cost around $50 million to make, and Polyphony's Gran Turismo 5's budget is rumored to be around $60 million.
