Im playing ESO from beta on and off with some breaks, but more I play more I think that that "lot of content" is just an illusion.
It feels really all the same, with every new DLC or big patch added: quests, which goes like "adventurer, we were attacked, please help us and kill baddies", main quest with hidden modern feminism bs, where "strong independent" woman leader ask you to run various errands to finally exterminate some daedra worshipers and lastly dungeons and raids, which are thrash mobs/boss/thrash mobs/boss/thrash mobs/final boss. And that's it. The rest is so minor (like housing, which dont have any deeper meaning in game) and maybe something else.
It is all on same rails every time, comparing to WOW , for example, where content really varies and differ, l even didn't bought Morrowind, because there was noting, except those quests I mentioned and warden class, which is one of the worst classes for now in game at every role.
Right now im spending most of my time in Maelstrom Arena trying my chances to get "Flawless conquer" title and absolutely have no urge/will to check out Clockwork content and its quests, because I already know what it will be all about…
It's a convincing illusion to me, in that case
While many quests will have similar elements - I feel the way they've integrated story and dialogue is vastly superior to anything I ever saw in WoW. Same goes for the way you can actually make meaningful choices that affect entire areas in the game - and you get to decide who lives and who dies.
In my experience, quests are very different in terms of story with lots and lots of variety. But the game is so big and there's only so much you can do with fantasy themes - and obviously you will hit upon similar notes around the world.
The writing is also actually quite good - not to mention consistent.
Now, I haven't noted any particular political direction - and I think the game has a nice mixture of strong male and female characters.
Also, being a very open minded and tolerant individual - I don't mind strong female characters and I don't see them everywhere because they're somewhere.
WoW, to me, always felt like a bunch of pointless activities with no real connection to the world or the characters. Too much silly stupid shit clicking balloons or picking up potatoes.
They improved that with the latest expansions - but it's still not at all compelling to me in terms of story and "meaning".
But you can take pretty much every game with a lot of content and boil it down to "repetition" - because that's what it will feel like with a certain perspective.
I played WoW to death for 3 years. But ever since exhausting TBC at some point back in 2007 - WoW has felt incredibly repetitive and overly familiar to me. But it wasn't like that at first.
Same perspective factor goes for Fallout 4 or Skyrim - which are both "walking simulators" full of pointless repetition to a lot of detractors - where I feel they're both full of rich and varied content.
That said, I'm not really into making everything into a competition. I like many of the things WoW has to offer. For instance, I really enjoy the sheer visual variety in the massive amount of zones that game has.
It's my favorite RPG of all time in that specific way - as each and every zone feels like a distinct world in and of itself. Might not be terribly realistic - but it's great for my immersion into the atmosphere.
However, WoW is just too stuck in ancient MMO mechanics and they're not fast enough to adapt to the way things should work these days. Times have changed - and so have the expectations of a modern audience.
The way they insist on making only the latest content relevant is a GIGANTIC mistake - and that's a big reason why I won't bother playing it.
I also feel the character system and perpetual advancement in ESO is vastly superior.
I could go on about features like thousands of fully voice acted quests with quality VA, stealing, murdering, housing, viable crafting, thousands of books/journals, meaningful end-game world PvP and so on that all combine into a much richer and more lived-in world than the themepark of WoW - but what would that accomplish.
Both games are great in their own ways - and it's all down to personal preferences.
