I'm surprised for that, do you not 'care about' the context of things in Genshin, for example?
It's a difference of approaches. I play solo games like the ones from Mihoyo for their worldbuilding, lore and story. I read all books, do all quests, go through item and character details, etc. In open world games like Elden Ring or GTA, I usually just explore and do literally everything EXCEPT for the main story. And only once I'm fully finished with everything else and literally HAVE to do the story - I'll get to it.
One of the bigger examples of this in somewhat recent history was in Metro Exodus. There's a location deeper into the game where you can follow the main quest or go a slightly different route. I obviously went to that other route and after several hours of exploration I came to a location that was supposed to be deeper in the storyline.
But devs accounted for my playertype and it the game just flown as if this was completely fine, even though I missed several fairly important character interactions and exploration points on the other route. I LOOOOOVE when games can do that, because it directly tells me that my playstyle is not just viable, but seen and is accounted for.
In more linear games, like AC6, I mostly enjoy the minute-to-minute gameplay. I'll still usually explore everything and go through text/audio logs and I will find them interested overall, but I mostly do that due to my completionist nature and steam achievement whoring.
But in pvp games (and I attribute mmos here, because those are the mmos I wanna play) - players are content. And in a PvX game like Ashes or L2 - players AND mobs are content. I added puzzles to that list, in my original response to Noaani, mostly cause Genshin created a certain love for them in me, so if there's some interesting puzzles in the world - I'll see that as content as well.
But as I said, if my preferred content is locked behind quests in an mmo - I'd rather if it wasn't. Though, on that note
Even if Quests are not 'content' for some, good quality ones are at minimum, context. RP-ers benefit from these in Fantasy games, where the player is often insular and the world doesn't change as much. This might be your L2 bias again (I have a matching FF11 bias).
But the effort to 'give you a context' can transform a normal activity.
I'm more than fine sitting through text or npc walking or whatever, because, as I'm sure both you and Noaani know, I'm all about middlegrounds. If all that additional stuff keeps more people in the game - better for me, because the world will feel more alive, and I play mmos for that kind of world.
I was planning on making a video (and still might, though who knows when) about early stage player markets in Ashes, in the context of L2's newest trendy server. Here's me running through the markets in a few starting towns. Server was 3 weeks old at this point and in terms of player progress, I'd say even the hardcorest dudes are somewhere around "lvl20" (in Ashes terms).
But markets are huge, ranging from starter gear all the way up to "lvl20" stuff. And a shiiiitton of materials trading, with ranging prices of "people buying for cheaper in starting towns, while buying for noticeably more in higher lvl ones".
I start showing stuff in the Elven starting village and go up to town where lvl10-20 people hang around. Didn't show lvl20+ town cause its market is way smaller, and also I kinda forgot about it in the moment

But to me THIS is also content. Playing the market, participating in it, simply benefiting from it - all of that is just "players are content", as, imo, it should be in a pvx game (Xness comes in from the fact that all of those items are from mobs that can be/have been contested).
I kinda treat PvX mmos like I did dota. There's mobs, there's players, there's secret/side shops - all of them are content and player-driven content happens around them.
All the non-PvX mmos I treat like story games. When I played a bit of WoW classic and FF14 - I read all the quests, interacted with pretty much every npc I saw, explored the world as much as I could and did every quest I could find.
