Something Old: I am torn between a world map, and turn based systems. The world map I want for just the pure joy of exploration and finding hidden little places. Turn based battles because Square had that mastered, their active battle systems really haven't been very impressive so far, and has felt clunky.

Something New: I would like to see them add to the world around them. Maybe rival hero's that will take your quests if you wait to long to do them. Or possibly have the NPC's have more of a life then the... "Hello, I run the inn. It will cost you 25Gil a night. Would you like a room"?

Something Borrowed: I first saw this in Breath of Fire II, then saw Skyrim do this well also with their Hearthfire DLC. Build your own homes and towns! A custom area for the hero's custom built bye the player to his likes. In Breath of Fire II's case, The town doubled as the airship if you showed mercy to a man who ended up being Ryu's father.
