The storyline and plot of Tactics are based in a medieval-like time with a twist of newer aged technology. A struggling royal family is without an heir, and they are being used by multiple factions seeking power. Figureheads, scapegoats, and manipulators plague the land, and truth and justice are hard to find. As with many Final Fantasy games, the storyline takes many critical turns - for the better. In too many cases, RPGs end up with exaggerated storylines; but this isn't one of them!
The characters in the game are very complex, and the emotion/relationship development is uniquely good. We follow many of the main characters from their childhood into adulthood. I do not wish to give any of the game away, but this is undoubtedly one of the best storylines in any game.
The gameplay and battle system in Tactics are also complex; and in some cases, hard to learn. It combines turned-based strategy with some effects that were very good at the time. It includes many of the magic and summons used in other Final Fantasy games, including Bahamut and Titan. The storyline is linear, but there are several side quests and hidden aspects of the game which give it replay value. These aren't the only things that give it replay value. The skill progression and job system in the game offer a near unlimited number of character tweaks and specializations. Working towards job levels by gaining JP (job points) unlocks new abilities, counters, movement tweaks, and passive skills. Building job levels also unlocks newer jobs, which then further adds to the complexity and fun of the game.
All-in-all, Final Fantasy Tactics is a one-of-a-kind game that I can't seem to put down for more than a year. Any video game fan should give it a try, and any RPG fan should make it a must-have. You will not be disappointed.
