have stronger artificial intelligence than real-time strategy games, since the turn-based pace allows more time for complex calculations. But a real-time artificial intelligence makes up for this disadvantage with its ability to manage multiple units more quickly than a human. Overall, real-time strategy games are more action-oriented, as opposed to the abstract planning emphasized in turn-based strategy. The relative popularity of real-time strategy has led some critics to conclude that more gamers prefer action-oriented games. Fans of real-time strategy have criticized the wait times associated with turn-based games, and praised the challenge and realism associated with making quick decisions in real-time. In contrast, turn-based strategy fans have criticized real-time strategy games because most units do not behave appropriately without orders, and thus a turn-based pace allows players to input more realistic and detailed plans. Game theorists have noted that strategic thinking does not lend itself well to real-time action, and turn-based strategy purists have criticized real-time strategy games for replacing "true strategy" with gameplay that rewards "rapid mouse-clicking". Overall, reviewers have been able to recognize the advantages associated with both of the main types of strategy games. Strategy versus tactics Most strategy video games involve a mix of both strategy and tactics. "Tactics" usually refer to how troops are utilized in a given battle, whereas "strategy" describes the mix of troops, the location of the battle, and the commander's larger goals or military doctrine. However, there is also a growing subgenre of purely tactical games, which are referred to as real-time tactics, and turn-based tactics. Game reviewers and scholars sometimes debate whether they are using terminology such as "tactics" or "strategy" appropriately. Chris Taylor, the designer of Total Annihilation and Supreme Commander, has gone so far as to suggest that real-time strategy titles are more about tactics than strategy. But releases that are considered pure tactical games usually provide players with a fixed set of units, and downplay other strategic considerations such as manufacturing, and resource management. Tactical games are strictly about combat, and typically focus on individual battles, or other small sections in a larger conflict. Settings and themes Strategy games can take place in a number of settings. Depending on the theatre of warfare, releases may be noted as naval strategy games, or space strategy games. A title may be noted for its grand strategic scale, whether the game is real-time, or turn-based. Strategy games also draw on
