Is the controller you get usable for the downloaded Nintendo games? I never bought an original classic controller and was looking at getting one in the next month or so, but would rather go this route and save a few bucks. Also, how much of the battle setup is like FF12? That's by far my favorite FF game. I wasn't really interested too much in this, but some of the videos I've watched make it look like this game is super expansive and could be fun, but I'm waiting until I figure out more about the battle system. Any ideas on time to complete with or without doing the side missions?
It's fluid and command-driven, like FFXII, and shares some of the UI elements: Little visual indicators of which character enemies are targetting, for example. On the other hand there is no option to pause to issue commands (except under special circumstances); you must act and react in real time. The game supports this by somewhat reducing the number of total abilities available to a given character in a given battle (though you start out with a fuller slate than with FFXII) and by making those abilities clearly visible and quickly selectable across the bottom of the screen by round icons. Most abilities operate strictly on a cooldown system, similar to games like World of Warcraft; a "mana" type resource is more or less disposed of here. Also, almost all abilities fire off immediately; the concept of "cast time" sort of disappears into very short animations.
There are multiple other bars that fill up or drain down, roughly similar to "Quickenings" or limit breaks in FFXII in function; they fill up as you successfully perform in battle, and then can be expended to cause powerful effects, or activate "chain attacks" that effectively stop time and allow the player to select an ability from each character in the party for one massive offensive or to buff up and heal. Outside the chain attacks you only directly control one character; the others use their particular abilities intelligently. There is nothing equivalent to FFXII's unique Gambit system, unfortunately, but the AI characters are generally pretty smart.
Like FFXII, buffs and debuffs play an important role in success. You must know what type of attacks (physical, magic, and so forth) will be effective against an enemy and beat down their defenses with debuffs if necessary; you must cleanse debuffs from your own party (or allow the AI to do it with one of the other characters). Unlike FFXII, positioning around an enemy is very important. One of the first characters specializes in backstabs and side-attacks, and gains bonuses if you're standing in the correct place for the correct attack. The game provides escalating debuffs in the form of Break > Topple > Daze, which gradually disable an enemy and make them vulnerable while halting their attacks on you.
Finally, the game uses a unique "prophetic vision" feature. Against many named enemies and almost all bosses you will be granted "visions of the future" before the most devastating attacks occur. They show you what attack will happen, who they will happen to, and a countdown timer. You have to figure out how to stop, avoid, redirect, or straight-up survive the attack before the timer runs out... sometimes easy, and sometimes not. It's a great strategic addition to the already frantic battle system.
