Well, yeah, I guess it depends on the enemy, and the game.
But in general, I find myself more dependent on my sword than most people. A lot of people use all kinds of their different weapons to kill enemies that can be killed with the sword, but in most games I rarely use an item other than my sword for an enemy that can be killed with a sword.
Obviously, there are some exceptions. First of all, any enemy that cannot be killed with the sword. That's pretty self explanatory. Some other examples are Pols Voice in LoZ, who I use the bow on, and most enemies in TP that can be killed with the ball and chain
The items that I am primarily using when I'm not using my sword are the Megaton Hammer, Skull Hammer, and Ball and Chain (in their respective games) and the bow, especially in instances where you can snipe, such as Hidden Village in TP, and the big fight with Moblins and Darknuts (specifically Moblins) after you get the Master Sword in TWW.
