I guess the tuning of the game. With Sekiro there was, for the most part, a general linear path that you did to complete the game. You could go in some different ways but for the most part it was linear. With Elden Ring you can go in any way and as people have said, if you get stuck, go somewhere else and get higher level and go back. But I don’t like leaving so I would proceed to get dumpstered over and over and get frustrated which is entirely my own fault. But, in Sekiro it seemed like the difficulty of the encounters were created in regards to where you were in the story and even though they were hard, were better tuned to your character power. I bet co-op would be a ton of fun and could make my play through more enjoyable if I got back into it.
