These gamss u mention, are developped in 1 direction they deliever 1 type of content and progress that type of content. Mmorpgs dont work this way they expand several types of content continously.
Which is why your comparison is unfair.
Maybe you play WoW but dont engage with raids or m+. So ur looking at its content from a lense of only open world content.
Or maybe you only do m+ and dont do open world content or raids.
The content will naturally be alot smaller, because its development is split among several end games.
Its value depends on how many hours a week you play for, thats the thing. So its value to me snd you will be different.
Gta aint designing raid bosses
Eve isnt designing dungeons.
Diablo aint developing pvp and raids.
Your comparing games which develope in one path to a game that developes multiple. Mmorpgs are a jack of all trades. These games you mention may make more content you engage with, but they dont make more content overall.
When you break down.
Open world
Reputations
Proffessions
Dungeons + additional difficulties.
Raids + difficulties + mythic phases.
Mounts
Achievements.
Toys / pets.
Lands / art.
Cosmetics / transmog.
Loot systems
Story.
New classes.
New races
PvP.
Warmode.
Theres just more in all of these content wise. Then what these games are delievering its just the entirity of gta is dedicated to 1 playstyle. Same with skyrim, same with elden ring, same with diablo 3, same with no man sky.
No maybe you dont engsge with 3/4s of the systems that maybe the case, but you cannot deny it as content just because you dont personally do it.
WoW makes more content. Its just there are players who ignore parts of the game and then screech that the content dont exist, when it does.
Gta in 2 years gave capture the flag and 4 new guns. Their largest out churn of content was 2017 and even then it was minor things realistically added.
Eve most of its updates are store deals and new stuff on the store.
Diablos is just turning on and off the next seasonal events snd moving things in which catagory they are in.
This sounds more like “these games add more content which i personally want” rather then “these games create larger quantities of contrnt”
WoWs value depends on how many hours u play entirely. If yoyr playing 4 hours a week its obviously not high value as a example.
That doesnt mean the game should be cheaper this silly notion of “make less money but retain the same quantity of content” dont work, the content will drop with its profits as they will fire devs to levy out of the losses.
The games model is absolutely fine. Its just theres alot of people who sit in the game. Only doing 3% of the games content screeching their aint enough content snd wondering why theyre met with a echo of telling em theyre wrong.
