Finally getting around to replaying the Witcher 3 on Death March difficulty. It's unbelievable, definitely the best game of the generation. one of the best things is that playing it on the hardest difficulty doesn't just make the game annoying or unfair like a lot of games, but instead forces you to utilise the games incredible systems of potions, oils, research and the like that frankly isn't really required if you play on normal. You can't just hack and slash your way through a throng of drowners, you need to have necrophage oil, maybe drink some potions or decoctions, make sure you use the right signs all the time and dodge your way around looking to isolate one and take advantage of an opening to get a couple of hits in.
Every battle becomes an ordeal, a bit like Dark Souls but with more prep you can do. The only downside is the game takes aeons to reload after you die, which happens quite a lot on Death March.
