We know that Sora will be able to have up to five members in his party in Kingdom Hearts III. I'm wondering if that's the limit, because I think there should be at least one battle with all seven Guardians of Light fighting together.
I just started this game a few days. I've already read the main plot doesn't really start until you've done 100 Story Missions. How many are there all together? I plan to only play about ten each day or less if my AP runs out first.
