Sarkus filled it in exactly.
And no, Turin, it doesn’t excuse bad quests, but a branching quest doesn’t exactly equate to a “good” quest either. Usually when someone says “branching” it means “end the quest by doing this, or choose to end it by going here and doing this.” After that, it’s up to the game designers to open or close other quest lines, and indeed that is something that this game does.
And with a game this open, with so many things you can do, where going to fetch something means walking through the most beautifully realized fantasy world ever made since Betrayal At Krondor or Ultima 7, all quests of that nature are automatically given a bump in quality because of it.
You know when “collect 10 bear asses” is something you don’t ever want to see anymore? Well in this game, you don’t just go to the BearHaven Woods where bears are on an infinite respawn timer and collect 10 asses, and for a good 15 levels of the game bears can readily hand you your shit if they suddenly attack you because you didn’t realize they were there. No, bears are not that plentiful, they’re not easy to sneak up to, their hides weigh 2 lbs EACH, and if you just let the quest sit there you’re very likely to go 5 levels without killing 10 bears.
I know where bears are in WoW. In The Witcher I knew where to go to find other shit that popped up the moment you exited and re-entered the area. But in this game, hunting bears means exploration through dense beautiful forests, and that exploration brings with it god knows what other things that grab my attention (and the world is so god damn rich in locations that this happens a LOT). I actually have a bear pelt quest, and it’s been a couple weeks in-game time, I go back to a cavern where I knew there was a den of bears, and they are all still dead. This isn’t WoW treadmill 101.
So if that doesn’t tickle your fancy, and if sticking on a main quest line that doesn’t ask you to grab 10 bear asses but rather challenges you as you level up also doesn’t tickle your fancy, then go buy one of those other games where you run into glowing markers and see numbers pop up as you do ridiculous shit with no repercusion in a world that is literally 1/20th of the size of this one and STILL not as detailed.
This game doesn’t exactly break new ground in any one part of its systems, but taken as a whole, this is a full step evolution in how fantasy RPG systems interact to make the player feel part of something else, instead of making them feel like they’re the center of the universe.
Took me quite a bit of willpower not to click on your spoiler, because as a burgeoning assassin I don’t want to already know how to get into the special club.
