Fullmetal Alchemist: Brotherhood, Fate/stay night: Unlimited Blade Works Recommendations
Both are epic animes dealing with magicalchemy or alchemymagic and transition circles also they both have great characters that overcome by the time,Fate zero is darker than FMA but both have amazing plots plus similar Themes
Animes where "People Don't Die When They're Killed"!
# where the protagonist seeks a powerfull mysterious mythological object
# where sacrifices are required to save people
# where the antagonists have different motives like greed, lust, pride...
# where a battle needs more strategy then pure strength
A dark non-episodic deep epic story full of action with great animation & soundtracks.
If you have heard of Fate/UBW, then you have probably already watched Fullmetal Alchemist: Brotherhood.
But if you haven't...then you gotta WATCH IT ASAP!
So I actually watched UBW then Brotherhood, and I was really happy I did in that order as well. Here's the thing: although they are not similar at face value, they pack the same punch. So, I guarantee if you enjoy one then you will enjoy the other.
(Note: I did not watch the original adaptation of FMA because most of my friends recommended that I would personally like Brotherhood better).
