<div style='font: 11pt arial; text-align: left; '>It did the whole in-battle-party-member-swapping thing way before FFX (and on the PSX no less). Also it had an intertwining subplot in which you would play as the resurrected emperor Fou Lou (and ONLY Fou Lou) - which was also interesting because very rarely do you get to play with a one-member party in an RPG and still have it be interesting.
The battle/weapon system is also very cool, I think. Each weapon has a power stat and a speed stat, and generally the stronger the weapon the slower it is - so you can bust out a sword that does a lot of damage but it will also miss a lot more often than a smaller sword. There's also weapons that are weak, but hit multiple times in one attack so if you miss one attack you still get a chance to hit with the other and at least pull off about half the normal damage. Missing attacks seems to be a big part of BoF too, which is something I like because it forces you to use the proper characters to hit the proper guys ("This guy's really strong, but he's slow so he should attack that big mutant boar instead of those wasps, and I'll have her hit the wasps because she's got good accuracy").
And on a personal note, I think BoF4 has the greatest character designs of any video game ever (well, it's a tie with CT at least). I mean, come on, a walking, talking St. Bernard who happens to be a ninja? How much cooler can you get?
BoF3 wasn't THAT much like Chrono Trigger, I guess...but they use the forest music from CT (I'm not sure how they were even <I>able</i> to do that, but they did). Also, the background doesn't change when you go into a random battle and the enemies keep moving around which is something that was pretty much unique to CT until BoF3 came out.</div>
