The Settlers (also known as Serf City, original German title Die Siedler) is a slow-paced simulation computer game by German developer Blue Byte Software, first released in 1993 for Commodore Amiga and in 1994 for the PC. The first in The Settlers series of video games, it was the first game of its type, blending together principles which had not been seen in a single game before, and defined the line of the later Settlers games. On the hardware available at the time, the game could control a maximum of 65,536 individuals, all behaving autonomously.
