HOW to play them ?
I tried playing dark souls few years ago and couldn't reach anywhere with it....and then I tried playing Nioh 2 this year, I Barely beat the first boss with 10s of times trying and then after that no matter what I did I wasn't able to beat the monsters, they could kill with 2 shots and they are so fast it is inevitable to not get hit when 2 of them appears
Nioh is not Dark Souls. One is far more an action/loot game that require you to study bosses and repeat content for loot (not a bad thing), the other is purely a methodical read on bosses and exploration.
Nioh is far faster, DS is far slower, including Elden Ring and Bloodborne.
Only thing I can tell you is it comes with practice. I know I'm biased though, Monster Hunter is my favorite franchise and is quite literally based on the idea of studying varied bosses and defeating them for loot for hundreds of hours, so it's why I like these 2 franchises too. Same idea applies to Horizon, and why the next 2 weeks are insane to process for me.
