After reading the Ocarina of Time manga, I didn't have very high expectations. This book exceeded them... slightly.
This story has a new Link, distinct from the character in Ocarina of Time. The writers have clearly come a long way, as Link has much more personality and a few character flaws (which usually come down to childish impulse, but that counts for something).
If you've played the games, you'll find that many characters who once felt like game mechanics are now actual characters. You'll start to get a deeper understanding of their lives and what they actually do when they're not being objects. In that vein, if you were expecting Link to be occupied by a diverse cast of bumbling sidekicks that he'd met in the games, you won't be disappointed. I am a little sad to say that Vasu didn't make an appearance, though.
The Seasons storyline felt very rushed and skipped over a lot of the development in favor of hitting all the plot beats as quickly as possible. It had a lot of high-action moments, but the motivations for these moments often felt forced and unclear. It felt less like the game in that it had no real arc for problem solving: The dungeons weren't given a mention, and the Rod of Seasons was only ever used once.
The Ages storyline picks up right where Seasons left off, hearkening back to that "play both games back to back" premise that they were marketed on. It's the same Link, and the events of the previous story are remembered and reflected going forward. For a Legend of Zelda manga, this is praiseworthy. The story itself moved at a comfortable pace, exploring a variety of interesting characters and their motivations. It slowed down to give the reader a chance to appreciate the social intrigue and the motives that were actually involved in its central conflict. Ages also doubled down on the "problem solving" aspect, making real thoughtful use of the time travel mechanic and a few key items. Just don't expect any established laws of time travel to be consistently followed whatsoever.
I was pleased to find out that the story also included the secret epilogue that you only get for completing both linked games back-to-back. It was about as shallow as I expected, but the writers' attention to detail deserves credit nevertheless.
This Legendary Edition was a bit of a heavy read, but as it is technically a collection of two original books, this was to be expected. It certainly held my attention better than both volumes of the Ocarina of Time manga. I'd recommend this to anyone who can't get enough of the original Oracle games.
