Q. In Persona 3, the party member's AI wasn't too sharp, and to tell you the truth, there were times I became frustrated in trying to deal with it. What have you done this time around to improve things?
A. You have nothing to worry about. We've gone though and and done a lot of reworking with the AI algorithms, not to mention the fact that in Persona 4 you can also manually control each party member.
Q. About halfway though Persona 3 I grew tired of the random dungeons, what have you done this time around to better the experience?
A. We're still using random dungeons, but we've done a bit with these missing people that you need to search for in each dungeon. There are certain themes for each dungeon that have their own accompanying challenge. To better improve the tempo of the game we've gone through and reexamined the overall volume of a level, filled them out as much as possible while slightly reducing the size, and a bit of tweaking by reducing gameplay time by a slight amount. That, and beyond the fact you can now exit a dungeon at any point with a specific item or magic, progress through a level is saved so you can start over again at any point.
Also, unlike Persona 3 where dungeons where mainly just for exploration, this time around there's also Event Dungeons where key pieces of the story unravel. On top of that, after you've completed a dungeon there's other elements to look forward to as well.
