Civilization

Sometimes, a programmer comes out with a simple, yet brilliant idea. Take Tetris for example: in 1987 a russian guy designs a little game with falling tiles, and suddenly the "puzzle game" category is born, with hundreds of new titles like Welltris, Hatris, Klax, Puzzle Bobble... just to name a few. In 1991 a genius called Sid Meier, already famous for games like the wonderful Railroad Tycoon, released a game that rewrote the concept of "god-game", born a few years earlier with Bullfrog' s Populous; in this game you control a whole civilization, developing it from 4000 BC to 2050 AD, from the discoveries of alphabet and cerimonial burial to those of robotics and superconductors.
