1) Better control of the party members. I hate that they use up all the focus almost immediately in combat.
2) Overall view of the map. The mini map is fine, but I would like to see the rest of the world. You can use fog-of-war to blank out areas I have not yet explored, but I want to know where I have been sometimes.
3) Make it more like a real RPG. Let me choose what attributes to level up such as Agility, Will, Strength, etc.
4) Open up more of the terrain to explore. Staying on the road only is too Wizard of Oz like.
