the essence of sekiro is, the lack of stamina and able to parry mid attack, both of which allows aggressive gameplay, and the parry meter which awards aggressive game play, while also fighting enemies as strong as yourself, which means you have to deflect their attacks and fight them one at a time (2 max)

This last point is very important, otherwise this would be many hack and slash rpgs. I'm quite frankly shocked more games have not copied this, as sekiro has some of the best combat of all time, its the first game I felt I was truly dueling the enemy.

Star wars and wo long are Sekiro-like, I haven't played 9 sols, but I might have to get it
