James175: From the preview I get the impression that the game is voiced with some rpg elements or am I reading too much into it? How much story driven is the game? I very much enjoy a good story in a game.
There are minimal RPG elements in the game, you can only increase your character's HP by finding or purchasing certain rare items. Only one character is voiced, and only in certain cutscenes. The game is indeed story driven, and there are multiple decisions you need to make that lead to different outcomes, but these are not immediately obvious. After you finish the game, there is a New Game Plus feature that lets you go back and try different outcomes. The core of the game revolves around finding your way through an overworld and travelling to and completing "puzzle" maps in each area. It's in the overworld that you can interact with characters and where any story progression takes place.
