Final Fantasy 3 IS worth the $16 price tag for the following reasons.
1.) VERY high quality RPG experience.
2.) AT WORST 40 hours of game play...if you are trying to do things the super hard way. If you do it the slow and steady way, 60-80 hours worth.
3.) The Jobs system means that you have 23 different ways per character for four characters to experience the game.
4.) NO IN APP PURCHASES!!!! You buy the whole game the first time and you play it as long as you want and can get every option.
5.) Finally, a game from square soft, which if we support will lead to more ports of square soft games. YAY!!!!!!
