In addition, great spy stories are not limited to spy fiction set during the Cold War but can extend to different periods and genres. It has much to do with the story, presentation, and setting.
Of course, having a game using themes based around espionage is more than just implementing good stealth mechanics. They are designed to challenge a gamer in different ways than explosive and fast-paced action shooters like Call of Duty and even Doom.
The stealth and espionage genre in gaming is usually a much more thoughtful experience than run-and-gun action games.
