Game: Phenomenon: City of Cyan

Why aren't there more sci-fi hidden object games? Is it because the genre's innately historical, and sci-fi is generally futuristic? Or is it that hidden object games are mostly played by women, and women don't gravitate toward sci-fi? In any case, it's a shame more games don't adopt sci-fi's unique themes. Then again, the new hidden object adventure Phenomenon: City of Cyan gives it a shot and fails miserably, thus demonstrating how difficult changing genres can be.
