Hahaha, that's awesome, mate! You're right, the "" define the positions of the characters in the party. Technically, you could create a party of 20 members and still enter combat, but everything else might break since the game wasn't designed for that.
And hey, if you're into meddling with files, don't stop at just the save games! I'm uploading updated documentation on dialogues, so you can tweak and create whatever you like. If you come up with something cool, I'd gladly consider adding it to the game. =D
Cheers!
