Glad I could help inspire this! I really like reading WHY someone loves something. Helps clarify, especially when it's not an every day title.
I already explained in the top games list why Mass Effect was my favorite game of all time, and because I doubt anyone wants me to repeat myself, I thought I'd take the opportunity to say that I love the Legend of Zelda franchise. Before Mass Effect, it was my favorite game series for about 18 years.
The original Legend of Zelda is a CLASSIC...but I actually find Zelda II The Adventure of Link to be a superior title.
That's right, I prefer Zelda II over the original.
The original game is a masterpiece in every sense of the word. Hands down, a landmark of game design. But in the years since, I think that other titles in the series have taken that formula and greatly improved. A Link to the Past is arguably one of the top games ever made, and the Minish Cap took the groundwork laid by these and ran away with it. My point is that the original LoZ was so good that they emulated it over and over. And I think it has been done better since.
Zelda II is unique. There are no titles in the series like Zelda II. Some are similar, in terms of learning abilities, etc. But a side scrolling RPG would never again be used in the Zelda series. And I don't fully get why.
I didn't always feel this way, but over the years I have played the LoZ style so much that the original lost some of its magic. When I want to play a top down Zelda I jump to LttP, Minish Cap, the handhelds and maybe the original. These days I have way more fun playing this title than the original. I know it's not perfect, but it's fun. And it's hard. I can beat the original with my eyes closed. Yes, it's challenging, but you are strong enough at the start of the game to really beat the game. II has more of an RPG element which turned some people away from it. And I agree it can be annoying, but I really have fun powering up and sticking it to that freaky thing with the axe (those who have died a million times on this guy know who I mean).
The side scrolling feels more like a classic NES style. The various skills mean you have to adapt your play style and really think to overcome enemies. Yes it's a difficult game, but if you approach it with a strategy and not just run and gun, most of the difficulty is manageable. There is also a lot of variation on how you can go through the game. It's much more linear than the original, but all of them have been since the first.
This game has its flaws, and I am not saying it's the best ever made, but when I am in the mood for some good, 8 bit Zelda, this is my go to title.
