Hey, that actually would be a great idea.

The only problem is, FF1 was designed with little or no character interaction in mind. How many times did the characters in FF1 talk to eachother, or even say a word? Never, if I remember correctly.

If you were able to change each one of seven or so characters, you would alter their personalities, and ergo, what they say to eachother and NPC's and how they react to certain situations. For this, you'd need quite a few different character lines and story paths.

In FF1, you only had four characters and six classes to choose from. However, that meant that you had a whopping total of 4,096 different starting parties. Text might not take up a lot of space on a game disc, but it does add up when you have that many different scenarios. You'd have either a huge game requiring way too many discs, or a game with no character interaction at all (like FF1).

The only game I can think of to pull this sort of thing off well is Seiken Densetsu 3 - you have six characters to choose from for your starting party of three. Depending on which characters you choose first, second, or third, their amount of story is different (the first one you pick gets the most time "in the spotlight," the second when gets less, and the third gets the least of all). All in all, SD3 has 120 starting parties to choose from, and it does this quite well.
