Developer Introversion Software

DEFCON (stylised as DEFCOИ and sometimes subtitled Everybody Dies in the North American version and Global Thermonuclear War in the European version) is a real-time strategy game created by independent British game developer Introversion Software. The gameplay is a simulation of a global nuclear war, with the game's screen reminiscent of the "big boards" that visually represented thermonuclear war in films such as… From Wikipedia (CC BY-SA 4.0)

    DEFCON is a nearly perfect game for me. It has extremely simple mechanics from which strategic complexity can emerge. It has an aesthetic and atmosphere which synergize and augment its core gameplay, in which you make decisions eradicating millions of lives while witnessing only an '80s themed abstraction of the devastation unfolding, with dramatic sounds of radar and choking death played in the background.

Critics, per Wikipedia

DEFCON received "favourable" reviews according to the review aggregation website Metacritic. 1UP.com said, "This just may be the finest piece of 'budgetware' ever produced, with every bit as much to offer strategywise as RTS games three times its cost," praising the "elementary" interface and calling the strategic depth "enormous." 1UP also praised the visuals, calling it "one of the best-looking PC games all year." Edge said DEFCON was "worth it for the presentation alone." Eurogamer commented that it was "the least ambitious of Introversion's games in terms of design," and "its limitations are ones of the game's basic scope," while praising DEFCON "as pure and direct a game as its…
