For example, they could remove some of the enemies from the game (black knights / mini bosses) a and limit their movesets. Perhaps even re-positioning the enemies to make them easier to confront. It would make the game easier while also not ruining the real Dark Souls. To truly experience the game someone would have to play it on the normal difficulty rather than just being able to breeze through the game on Easy and memorize all the enemy positions and fighting styles.
