Fullmetal Alchemist: Brotherhood, Fate/Zero Recommendations
Set in a different world, where magic/alchemy is common. They are both fully packed with action, and are likely to leave you on the edge of your seat by the end of every episode. Whether you are looking for something with a similar plot, similar fights or something epic with that dark feel to it; Look up the other if you haven't watched it yet.
Both are mature action series that have a great set of characters, a good plot, and amazing art. Definitely recommended for action lovers who find Bleach/Naruto/One Piece too childish.
I can't see anyone liking one and disliking the other.
Both animes feature an outstanding plot and really great characters in a world of magic. Maybe Fate Zero is a bit slower, but some conversations between characters are simply remarkable, and I think that some characters (and voice actors) simply surpass FMA ones. But FMA is longer, and it's really epic.
Ok, this is going to be hard to explain, but first, I will and never compare brotherhood to a crap series. this series is good. Magic (Alchemy), well developed characters, world domination and survive of the fittest. Fate zero put in challenge the skills of their characters, fighting each other to achieve one goal. Same with brotherhood, where the alchemist, using their skill at their full, must uncover all the mysteries behind the ongoing events. Filled with mystery, thriller and action, these both anime wouldn't disappoint you.
Both series involve some mystical element whether that be full on magic users or a scientific form of modification known as transmutation. These series are, in my opinion, some of the best anime ever created with beautiful animation, compelling characters (both heroes and villains), with an excellent story. If you want to just laugh or chill then these series are not for you, with so many twists & turns these anime offer insightful questions about the essence of humanity. I simply cannot recommend both of these series enough because they are required viewing for anyone who enjoys great stories.
Both series use a non-medieval and interesting take with magic. Although, while FMA is in the 20s/30s, Zero is set in the 90s.
The Battle for the Holy Grail is much like the search for the philosopher stone except that it's more of a no holds barred tournament with very few rules.
Fate Zero's main difference is that it expands on the idea of kingship brought up in FMA Brotherhood and the cynical contrast to FMA's optimism.
