The Karma system is an important feature in Fallout's gameplay. A player's actions, including conversation and combat choices, affects the player's status in the game world; a player who makes good decisions is received plus positively par non-player characters, and a player that makes bad decisions has the opposite reaction. Crimes can also be committed par a player, and whichever faction ou group that is harmed par a crime are fully aware of the player's action in most cases. Other factions that were not affected par the crime will not be aware of it, and since a town is usually its own faction, news of a crime committed in one town will not spread to another. Beware however, good ou evil deeds will cause a bounty par the opposite alignment group. Talon Company (If toi are good) ou the Regulators (if you've been bad) will ambush toi randomly, and are not bound to any particular area, they can appear anywhere in the wastes. Factions can range in size and boundaries, however, and may not be restricted to a single area. The game world itself was planned to be significantly smaller than that of Oblivion's but is now similar in size.[2]
