The problem I find with the open world is how one dimensional it is. By the later open world areas its like - oh, another identical crypt, featuring two mini bosses you've beaten three times already for an Ash of War you can't use. In other games you'd also trigger plot exposition, quest progression or even just find some TACOs. Elden Ring rejects all of these, which is very on brand for From, but in not replacing it with anything but the same few experiences, it makes it hard to be as motivated to explore the later areas once the novelty wears off.
I was rereading some Berserk this weekend (which in case you don't know is a manga that the Souls games were heavily influenced by, if not entirely based off) and as well as greatsword welding combat with knights and monsters, it has freakish and arcane plot lines that don't really make sense but are kind of intriguing nonetheless. I really feel like From could incorporate some Berserk style plot development without losing the sense of mystery that comes with the other games. That'd give us a lot more reasons to explore - go into this dungeon to get an item to allow us to defeat a demon in another place, for example, or go in to free a character that's been imprisoned. They don't want to go down the road of lame Horizon style talky exposition and cut scenes, but Im sure there's some middle ground to be had.
