Sekiro is like the best sword fighting game. Like other fromsoft games it expects you to meet it on its terms. Unlike their other games you can’t really level your way past problems. Some people don’t like that. I love it. Mastering the boss fights is incredibly satisfying. The first serious boss fight took me all day the first time, but now I can do it without getting hit.
Elden Ring is very big and open, but has many options to make it easier. Leveling up, summoning help, summoning NPC help.
