A Link to the Past is my favorite. One of my favorite games of all time. Majora's Mask and Twilight Princess are both close seconds but ALTTP just felt the best (2D Zelda 4 lyfe!) Hoping to get a 3DS soon to get the Oracle games and Link's Awakening. I seen some Let's Play/Gameplay of them but definitely want to try them for myself. I also have beaten 4 swords adventures and while a very fun game didn't really stand out too much for me (God damn Tingle was always a killjoy). I have the original but it's way too hard for me and Skyward Sword which I dislike heavily. And finally I have Ocarina of Time which was also very fun. Oh yeah and Phantom Hourglass which was again, very fun (never understood the hate behind it, it's a solid game).
I think that about covers it.
I've completed most of Four Swords by myelf, nearing the end now and a friend joned in on it, which was really interesting and fun, I wonder how it would play with 4 people.
Yeah, I thought Phantom Hourglass was fun, haven't played it since release, but I remember disliking the main temple that you have to revisit like 3 times, going deeper and deeper real sneaky like.
