I agree. I have so much fun trying out new strategies in Tactics. Most of the other games are fairly well set into what you are suppose to do with each character where as Tactics, everything is up to you. Your party is entirely set up as you want it to be. You don't have to a be a Knight. You can be a Samurai, a Ninja, or a Black Mage. It takes the Final Fantasy series to a whole new level.
Thats why I love the game and have beat it some 30+ times.
