Shadow Complex was a bit of a special case budget wise. It's paid for by Microsoft and was a test case for high end UE3 games on XBLA, so further subsidized in that regard. It's like saying AAA 360 exclusives can be as cheap as $10m to make since that was the budget on Gears of War, it doesn't really reflect the financial reality for most game makers under normal circumstances.
Dead Rising: Case Zero is also a bit off, since it recycles assets and technology from the high budget Dead Rising 2. It's more a marketing tie-in release than really an independent ground up effort, if DR2 didn't exist Case Zero literally couldn't.
