According to ESRB, this game contains: Alcohol Reference, Fantasy Violence, Mild Langage
Parents don't have a lot to be careful of. I honestly can't recall the alcohol reference or the mild language, so I feel confident in saying that there was nothing excessive. Fantasy violence must mean firing a gun or getting hit with a grenade, though there's never any blood or gore… very chaste stuff here. The difficulty might make your kids squeal, but it's otherwise safe.
Strategy nuts might be thrown for a loop with the game's heavy action emphasis but it's worthy of having the word "tactics" in the title… it's just a different way of thinking. But if you're looking for Final Fantasy Tactics part two, you'd better steer clear.
Multiplayer maniacs get a pretty robust set of goodies and options. Choices of things to modify include team makeup, turn structure, all of the maps from the main game and more, though many of these features have to be unlocked by meeting requirements in Story Mode. I can't say the main game translates into the best multiplayer I've ever seen, but the effort is there.
