Tower defense is a subgenre of real-time strategy video games, where the goal is to stop the enemies from reaching a specific point on the map by building a variety of different towers which shoot at them as they pass. Enemies and towers usually have varied abilities, costs, and upgrade prices. When an enemy is defeated, the player earns money or points, which are used to buy or upgrade towers, or upgrade the number of money or points that are earned, or even upgrade the rate at which they upgrade. The choice and positioning of the personal towers is the essential strategy of the game. Many games, such as ''Flash Element Tower Defense'' feature enemies that run through a "maze", which allows the player to strategically place towers for optimal effectiveness. However, some versions of the genre force the user to create the maze out of their own towers, such as ''Desktop Tower Defense''. Some versions are a hybrid of these two types, with preset paths that can be modified to some extent by tower placement, or towers that can be modified by path placement. == History == A prototypical tower defense game was the Atari Games release ''Rampart'' in 1990. By the early 2000s, maps for ''StarCraft'', ''Age of Empires II'', and ''Warcraft III'' were following in ''Ramparts footsteps.〔 The Fort Condor strategy minigame in ''Final Fantasy VII'' may also have inspired the tower defense genre as it contains several elements that are now genre mainstays. Eventually, independent video game developers began using Adobe Flash to make stand-alone tower defense browser games, which led to the release of ''Flash Element Tower Defense'' in January 2007 and then ''Desktop Tower Defense'' in March of the same year. ''Desktop Tower Defense'' became immensely popular and earned an Independent Games Festival award, and its success led to a version created for the mobile phone by a different developer. Several other tower defense video games achieved a level of fame, including ''GemCraft'' and ''Plants vs. Zombies''. By 2008, the genre's success led to tower defense games on video game consoles such as ''Defense Grid: The Awakening'' on the Xbox 360, and ''PixelJunk Monsters'' and ''Savage Moon'' for the PlayStation 3.〔 Tower defense games have also appeared on handheld game consoles such as ''Lock's Quest'' and ''Ninjatown'' on the Nintendo DS. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「tower defense」の詳細全文を読む スポンサード リンク
