I mean... okay ? I really don't want to go on yet another "this is not a written kruggsmash video" explanation. You don't have to help if you don't want to help. That's ok; I'll manage, promise.
Not trying to start a fight, but he wasn't trying to compare it to one. He was saying the world is apparently bland and uninteresting by DF standards of crazy shit happening - although to be frank,
multiple wars in-progress and the repeated werebeast attacks suggest otherwise at least in my opinion. If nothing else there seems to be a plague of apostasy/unchecked monsters/stupidity abounding with those weres still menacing the countryside.
One could even wager that the multiple wars and the civil disruption that entails is leaving the various kingdoms unable to effectively fend off such hazards, as the bulk of thier troops are on campaign or guarding "more important" centers instead of protecting the outlying hillocks, minor retreats, pits, and hamlets.
I've looked through quite a bit of legends, and I've come to a conclusion:
This world isn't all that interesting.
Pretty much all the interesting history is stuff you've already wrote about. 125 years of worldgen isn't very long, the world isn't very big, and the world was generated before a lot of the interesting legends stuff got put in. There are no vampire tyrants, colossal battles, conquering generals, or legendary heroes. I've always been more of a historian in my approach to legends rather than a storyteller, and this world has me stumped.
The world was also genned with mostly-vanilla files (I think I read somewhere Cathar only did the minimum to make humans playable,) and I'm assuming the world was generated with pop caps, in which case insane/super interesting stuff is simply
less likely to happen anyway because populations are limited to draw on for victims, perpetrators, and armies. The super-modded, no-cap worlds I gen at minimum tend to be rife with at least a couple extermination wars and plenty of megabeast/semi-megabeast attacks, and I usually only run a world for between 190 and 240 years - not really all that much longer.
That being said, it's not that interesting stuff isn't happening - The River Crossing has their civ's first and only cavern breach (albeit under-utilized, again in my opinion,) have killed at least one Forgotten Beast, and have fended off several intrusions. In-universe that'd all be considered a huge deal, it's just not gonna be that remarkable when compared to world-spanning wars of attrition like those that raged in Tholtig Cryptbrain's world, or finding that one guy who made a career out of slaying megabeasts or similar such things.
EDIT: Not trying to start a beef to be clear. Just wanted to offer my two cents here.
