In a game like Zelda the strategy comes done to which item or weapon is useful for the given situation, and to a degree how well you use it.

A turn-based game thrives in situations where thought must really be put into every move -- behind every move is a strategy instead of reflexes and so on. When you have multiple enemies to choose from, using certain attacks requires certain resources, and especially when you want the player to control multiple characters at the same time, turn-based is almost definitely the way to go.

IMHO turn-based games could benefit from simultaneous moves -- that is, you and your opponent each choose a move, and then they are performed simultaneously. The success of each move doesn't just depend on the strengths and weaknesses of the opponent, but sometimes on the move they used at the same time. I personally think turn-based games that limit themselves in other strategy (if there's only one target to attack, and/or there's only one player-controlled character in the battle strategic options are significantly reduced) could very easily add significant strategic depth through this.
