No, i've never played any of the FF games. Are they good?
Depends if you class menu-based battle systems for gameplay as fun games or not.
FF1 isn't too bad. Plot's pretty basic, though. The game uses a turn-based system. Meaning that you have loads of time to plan your actions out before the enemies attack you.
FF2 is considered to be the black sheep of the series. While it is the first in the series for characters to have their own identities and personalities, the leveling up system is not something to be desired. Avoid it, if thou lack patience.
FF3 has a job system. You bestow different fighting classes to your characters.
FF4 is the first game in the series to have the active time battle system (ATB). The enemies still hit you while you're busy trying to figure out what to do next.
FF5 is basically a combination of FF3's Job system and FF4's ATB system.
FF6 is the last major 2D FF game to date. You have more characters than the standard four, which gives you the opportunity to split them into groups depending on where you are in the game.
FF7 is for the mainstream gamers. Overrated trash.
FF8 and onwards are overrated.
