This is true. In that sense it’s less on rails in terms of zone progression, but it’s still a quest-driven follow-the-breadcrumbs themepark approach that WoW popularized (although I think ESO does it the best and retains much more feel of a “world” with things to explore than any of its contemporaries).
I can’t speak for @milspec, but I agree with him that this game is much less on rails. I’m probably going to do very poorly in describing what I mean, but Shroud feels much more open in design. While you can go into any zone in ESO now, there’s still more structure there. You follow the ^ on your compass to grab the quests, go to the ^ to complete them. You look for skyshards. Then you move on to the next zone and repeat. This is probably a good thing for a lot of people’s tastes!
Shroud feels wide open. You wander the world map, enter adventure zones, and just kind of explore. Most of the areas that I’ve seen don’t have quests directing you, it’s just exploring and figuring out what might be at the bottom of that cave: maybe nothing, maybe a treasure chest, maybe a locked door you don’t know how to open.
Here’s an example. I was wandering in a zone, mostly looking for a good place to chop pine trees for a carpenter/archer friend who is playing the game as well (he needs the pine for arrow shafts). While I was exploring, I came upon a fortified bandit camp which had guards fighting a bunch of undead that were coming up out of a ravine. This wasn’t a scripted set piece where they’d sit there and bash each other endlessly, this was just a situation where some undead spawned and wandered too close to the camp. Bandits hate undead, thus the fight. A bear even wandered by and tore a chunk of an archer’s butt off while I watched.
Anyway, I took that opportunity to break into the camp. It was hard fighting and I was in over my head, having to retreat a couple times. But I was eventually able to utilize undead and some aggressive fauna to force my way in and kill the bandit captain. On his corpse I found a key, but I had no idea what it was for. In ESO or other MMOs, this key would be marked “QUEST ITEM”. I would right-click it and get instructions. That, to me, is the more “on rails” part. Not the case here: I had a key, but no idea what it went to.
I left the camp and began exploring the woods, and I found a vault with treasure locked behind it. Ah-hah! I went to use my key and… nope. Hmmm. Maybe I missed something in the bandit camp?
I made my way back to the camp (I should mention that in solo/party areas, monsters don’t respawn. Things stay dead when you kill them, so you can work your way through a zone) and explored around some more. I went into the captain’s tent and took a closer look. On the table were a few various items, a candle… and a note. Nothing draws attention to the note, it’s just sitting there on the desk like any other item. But I read it, and it’s discussing the locked vault and how the bandits have each taken a key, so that they can only get into the vault when all three of them can open it.
So now I know how to get into the vault, I just need to find the other bandit captains. I can’t pull up a map to see a highlighted area where they are, I have to do some legwork on my own and find them. And while I was doing so, I found a cool cave that was full of amethyst and diamonds. Shiny! Unfortunately, as I stepped into the cave I realized these orb looking things on the ground weren’t just decoration, they were in fact spider eggs. And when I approached, they burst. Swarmed by spiders, I was doing okay until a giant wolf spider webbed me and made me its dinner. Before I died, I also noticed that the cave went further down… was there something more down there? Oh crap, now I’m completely sidetracked, I was supposed to be looking for bandit camps, but now I want to explore this spider cave!
That, to me, is what makes the game feel much less directed or “on rails”. It reminds me much more of something like UO where I’m discovering my own adventure. Some people (a lot?) might hate the lack of direction, outside the main quest, but I really enjoy that kind of experience.
