The game was originally developed for MS-DOS running on a PC, and it has undergone numerous revisions for various platforms. The player is tasked with leading an entire human civilization over the course of several millennia by controlling various areas such as urban development, exploration, government, trade, research, and military. The player can control individual units and advance the exploration, conquest and settlement of the game's world. The player can also make such decisions as setting forms of government, tax rates and research priorities. The player's civilization is in competition with other computer-controlled civilizations, with which the player can enter diplomatic relationships that can either end in alliances or lead to war.
Risk is a strategy board game of diplomacy, conflict and conquest for two to six players. The standard version is played on a board depicting a political map of the world, divided into 42 territories, which are grouped into six continents. Turns rotate among players who control armies of playing pieces with which they attempt to capture territories from other players, with results determined by dice rolls. Players may form and dissolve alliances during the course of the game. The goal of the game is to occupy every territory on the board and, in doing so, eliminate the other players. The game can be lengthy, requiring several hours to multiple days to finish. European versions are structured so that each player has a limited "secret mission" objective that shortens the game.

In video games, artificial intelligence (AI) is used to generate responsive, adaptive or intelligent behaviors primarily in non-playable characters (NPCs) similar to human-like intelligence. Artificial intelligence has been an integral part of video games since their inception in the 1950s. AI in video games is a distinct subfield and differs from academic AI. It serves to improve the game-player experience rather than machine learning or decision making. During the golden age of arcade video games the idea of AI opponents was largely popularized in the form of graduated difficulty levels, distinct movement patterns, and in-game events dependent on the player's input. Modern games often implement existing techniques such as pathfinding and decision trees to guide the actions of NPCs. AI is often used in mechanisms which are not immediately visible to the user, such as data mining and procedural-content generation.
