1) Ocarina of Time - I have lots of great memories with this game. The music is INCREDIBLE as well. I also love the story and the dungeons are just FUN! The art's great, too, and is my favorite game. Ever.
2) Wind Waker - I also have good memories with this game, and I thought it was a very fast-paced game, with the exception of Triforce shard hunting. I liked the Great Sea, but it sometimes got boring sailing around. I love the cel-shaded graphics and the expressions Link makes. The dungeons were also very fun and I liked the Deku Leaf.
3) Spirit Tracks - Yep, it's easy. Yep, it's pretty short. Yep, that doesn't make it any less fun. I love having Zelda around, even as a spirit, and the train was fun. The overworld music was my favorite from this game, and I liked the Spirit Flute, bringing back music from Ocarina of Time.
4) Twilight Princess - I'm not far at all in this game; I'm only at Kakariko Village, but what I've played is very good. It's a little too dark for my personal liking, but it brings a new look at Hyrule. Midna is also awesome and I think the art and graphics are amazing.
5) Majora's Mask - Like Twilight Princess, I've barely played this. Actually, I haven't even found the first shattered fairy! I got too scared by the moon that was about to kill us all so I freaked and hit the power switch on my 64.
I'll play this game ASAP though to write about it and review it. What I've read about this game (which is plenty) makes the game sound incredible. I know the 72-hour concept was born out of an 18-month time limit, but it brought something new to the table, along with the different masks. I really can't wait to play this game!
Other games that I'm looking to buy are Minish Cap and the Oracle Games. I have a feeling Minish Cap will be on my list when I play it.
