That is fair. But I am still not convinced they are as hard as they are made out to be. I think it is a lot of tire pumping by guys who played it trying to show how good they are at video games.
But, yes, a walkthrough open while you play is not a bad idea at all. I dont have a PS5, but if some of you do, then you can also check out Demons Souls. It will help you understand how Souls games work with more linear progression so you arent just thrown into the world with no understanding of what to do and where to go.
They're not "hard" in the sense that every enemy has a pattern of attacks/certain tells before attacking. If you can recognize what attack is coming you can be proactive or react accordingly. But if you don't have a good eye because these games are fast paced and very busy visually, or like someone said if Elden Ring is gonna be your first foray into From games, it might end up being extremely frustrating just for how punishing dying feels in the other titles. Most checkpoints are a considerable distance away from boss fights which is probably where people do most of their dying. You then not only have to take the time to run back just to get to the boss (where you can then get instantly one-shot from not paying attention from already being tilted from dying), you also have to 1) remember the correct way to go and 2) not die again on the run back. "Frustrating/punishing game design" gets confused with "Hard gameplay." These games, I feel, are designed to make you feel the immensity and gravity of events in the gameworld and for you to take your time as a casual player.
A walkthrough on the first playthrough would spoil any fun for me. A lot of the enjoyment in From games (again, for me) is the learning experience and overcoming something that felt like "impossible" wouldn't do the difficulty justice. I wish I could go back and re-experience Dark Souls 3, Bloodborne, and especially Sekiro for the first times and the feeling after smoking some boss I was stuck on for 6-8 hours. When I killed Nameless King in DS3 I popped all the way the f*** off. I didn't give a shit that he made me his bitch for an entire week, for a brief moment he was
my bitch. Same with one of the Corrupted Monk bosses in Sekiro. It felt like the entire rest of the game was unlocked after that.
I would recommend Sekiro as a starter From game. IMO it's the absolute most straight-forward, least customizable of their Soulslike games that almost totally focuses on your gameplay and learning the "dance" of fighting. No weapon choices, no armor choices, no spell-casting choices (aside from the prosthetics which I think are much easier to understand than 95% of how spells work in Dark Souls). Everything else gets a lot more muddy in DS/BB with classes and vague stats to increase and loot hunting for item upgrade materials. The only thing that could be a hurdle going from Sekiro to other Soulsborne games is that combat in Sekiro revolves around parrying attacks while DS/BB revolves more around dodging attacks.
My biggest piece of advice for newcomers to From games: Take your time with everything. When you fight a new enemy/boss, don't always go in guns/swords blazing trying to kill them before you see anything that they can do. Dodge as many of their attacks as you can and try to learn from the ones that hit you. Figure out ways to create distance during fights! Use your run button because you will need to use it often. This will help you "slow down" other encounters in the game because you feel better equipped to defend yourself.
