The Witcher 3 has a Death March achievement: Walked the Path, which means if you want to get the platinum trophy in The Witcher 3, you're going to have to play the game from beginning to end on Death March without changing the difficulty. This can be concerning for some players, but take it from a veteran of The Witcher 3: Death March is how the game should be played, and it's not even that difficult once you understand how the game works!
Death March has a greater challenge, but that actually makes the game feel more immersive. Since enemies are deadlier, you're forced to learn key systems, like Alchemy, Bombs, and Signs, and use your reflexes to fight, instead of just tanking hits and spamming your sword.
You'll feel more like a witcher on Death March, as you have to think and act as they do in the lore!
Death March can quickly become an easy (yet fun) experience as long as you get past the early stages. At around Level 10, Death March can become a breeze if you invest in your builds correctly with smart usage of Skills, Signs, Mutagens, and of course, your weapons and armor.
While you can play on any difficulty you're comfortable with, Death March is actually great for a first playthrough, as you will have to engage more with the challenge in front of you. Learning mechanics and crafting builds will be key to the experience, which is so much better than just running around with a sword that has high stats.
As you can see from the table above that compares Death March to Normal difficulty, these are what you can expect:
