ファイナルファンタジーV
"Final Fantasy V" is the second "Final Fantasy" game to use the Active Time Battle (ATB) system, in which time flows continuously for both the player and enemies during combat. This system was first established in "Final Fantasy IV", but in that game, there was no way to visibly anticipate which character's turn would come up next. In "Final Fantasy V", the player can see which playable character's turn is next in battle, in the form of a time gauge—or "ATB Bar"—which fills according to a character's speed. When the selected character's turn arrives, the player can execute one of several commands, such as attacking the enemy with an equipped weapon, using a special ability or item, or changing the character's row position. The ATB mechanic with a gauge, as seen in "Final Fantasy V", would be used in the four following main titles in the series and remains a staple mechanic of the franchise.
