So a few days ago I sat down to finally beat the original The Legend of Zelda on NES, which I was halfway through a playthrough of, only to find that my save data got erased. I double checked the saving ability and it still worked, so I thought it was a fluke, and started again. After randomly losing the data again today, I gave up and decided to play the Wii U virtual console version instead.
I ended up beating it in one day (took me 8 hours, according to my play log) with 100% completion. Thing is, I definitely used the Zelda Dungeon walkthrough for most of it, as well as save states for the harder parts toward the end (though I forced myself to not use them every second).
Generally I'm opposed to just playing an entire game from a walkthrough or while using save states, but I had already beaten half the game without it before, and frankly the game felt impossible otherwise. I understand the game was from a different time, and I love a game with a ridiculous difficulty setting, but even I have my limits.
The game is absolutely archaic by modern standards (putting required secrets in places where no one could ever possibly know to look without accidentally stumbling on it, etc), and most of the difficulty and "punishment" for failing is just artificial lengthening of the game with monotonous tasks. Id est, die in the last dungeon? Sucks for you, you have to start at the beginning with all the enemies respawned and only three hearts. If you want more, you're going to have to find a hidden potion shop. Oh, you don't have enough rupees to buy a potion? Fuck you, you're going to have to grind for 68 rupees, have fun (a process which can easily take 30 minutes or more, considering how rarely enemies actually drop anything compared to newer games).
In the end, i didn't enjoy myself that much (probably the least I've enjoyed a Zelda game, honestly), but I'm glad I played and beat it, if only to get it over with. Now to complete my playthrough of the entire series, I just need to beat Zelda II and Four Swords Adventures. Then I'll be all ready for A Link Between Worlds' release this November!
