Gears of War 2 had a $12 million development budget

[Reasonable]

That probably has extra costs because they did much more (and better) VO and motion capture for the cut-scenes, and for the second one they are adding in MP

Thanks, guess my memory's going when I remembered $30 Million for Uncharted!

As the article states the cost is the same as savings in core engine development are being used to deliver more content, SP, MP and Coop vs SP only, more levels, expanded production values on motion capture, etc.
