doesnt really look like it took that long to add on. just a bunch of generic and boring quests, and people are eating this right up. this is why procedural generated EVERYTHING isn't as "EPIC" or "AWESOME" as everyone thinks, because it's never done right and you're left with a dull and lifeless world. It's like they adopted mad libs for their quest system, and just had a script fill everything in.
"This pot needs ______, so go kill ___ and pick some up! Oh and when you're done some _____ will spawn, kill them and get ____"
"Kill some ____ in the forest than return to be and get a _____"
And they did it in the most boring possible way too. They actually had to keep skipping the combat because it would've been to tedious, repetitive, and boring to watch, and this is an ACTION game.
They could have made it interesting, like generate two kingdoms and assign random beliefs/customs to them, and generate things accordingly. If the two kingdom's have opposing values, it would generate a questline where you can side with one and help them defeat the other, which then opens up more quests and you're recognized as a hero. Or they can actually have a generated raider group that plans to attack the kingdom, and you either help invade or defend. The procedural system had potential to be really cool and make for some cool stories (see: dwarf fortress), but it just winds up making the world feel bland and boring.
