REAL TIME BATTLE!
The Real Time Battle (RTB) system is a battle system introduced in Final Fantasy XI and was designed by Akihiko Matsui, who created the battle system for Chrono Trigger. The RTB system replaces the Random Encounter that has featured in past Final Fantasy games, instead monsters are found freely roaming areas and are seamlessly engaged.
As the battle takes place without a separate battle screen loading one is free to move around the landscape during battles, interact with other players or avoid battles altogether. Monsters may also attack players without provocation, retaining a hint of random encounters. Characters start attacking automatically once they are in combat with an enemy, and special commands and magic can be inputted by the player at any time. Many items, spells and abilities used during battle have a casting time or delay to use once activated, similar Active Time Battles.
ACTIVE DIMENSION BATTLE!
The Active Dimension Battle (ADB) system is the evolution of the Active Time Battle (ATB) system and designed by Hiroyuki Itō, the original creator of the ATB system. It was first used in Final Fantasy XII. The ADB system eliminates random battles; enemies are fully visible on the field before they are engaged in battle and so the player has a choice of if they want to fight them or not.
The battles take place on the field with no separate battle screen and there is no transition between exploration and battle; ADB makes battles completely seamless. The system also includes the ability for the player to still have full control over character movement while currently engaged in battle. The distance between party members and enemies also influences battles as various spells and abilities now have an Area of Effect (AoE). The addition of AoE simply means that party members and enemies need to be within a certain range of each other for their spells and abilities to hit.
Almost all games have used this combat system that Akihiko Matsui and Hiroyuki Itō has created.
Actually their systems is almost completely identical at my first read through.
How can they patent so identical systems?
And here is ...
COMMAND SYNERGY BATTLE!
Command Synergy Battle (CSB) is the name (declared in-game) of the system used in Final Fantasy XIII and in Final Fantasy XIII-2, designed by Toshiro Tsuchida. It derives the flow of time from ATB as each character has their own ATB gauge. The ATB gauge in turn acts like an action point meter that's divided up into equal sections (a similar system was used in Enix's game Robotrek).
Each action consumes a portion of the ATB gauge, for example attacking consumes one point, while casting a powerful spell consumes three. Commands can be chained so as long as there's enough action points. When the player decides on what commands to take, the player presses another button to execute the commands for the character to do. If the player executes the chained commands without filling all ATB slots, the unused slots will be filled at the start of the next turn. Unlike regular ATB, the player is only able to control the actions of the party leader.
At the end of each battle, the player is judged on a rating of zero to five stars. In Final Fantasy XIII, this rating is based on a comparison between the party's power and battle duration; while in Final Fantasy XIII-2, only battle duration is ranked.
A game called "hero academy" is using this system.
Did they pay them?
