I have played almost every Zelda game except the new ones like Skyward Sword. Majora's Mask was the one I had the most fun in since I enjoyed collecting the masks, favorite mask in particular was the Bunny Hood because it makes you run and not walk so slow. Ocarina of Time was pretty great too, it was my first Zelda game and was quite the challenge. I struggled a lot when I played the game and there was no internet or guides in my house to help me but I still managed to beat the game. Wind Waker was also fun, I have played both the original and HD remastered version on Wii U. Twilight Princess was good, I enjoyed playing as Wolf Link and the whole game overall.
Still unsure if I should get Skyward Sword though.
