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 mais positively por non-player characters, and a player that makes bad decisions has the opposite reaction. Crimes can also be committed por a player, and whichever faction or group that is harmed por a crime are fully aware of the player's action in most cases. Other factions that were not affected por 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 or evil deeds will cause a bounty por the opposite alignment group. Talon Company (If you are good) or the Regulators (if you've been bad) will ambush you 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]
