Yeah the salmon are awesome, but there's a LOT of detail and often quite dark humour in the game as well, it has a lot of depth to it as an overall experience - the farmers leading the cattle to the giants, the cattle are painted, there are proper reasons why, the little abandoned shacks or shacks with corpses in who've just ...died...
It's a living/dying world.
Brilliant.
Ah yeah, I've seen that (The farmers leading the sacrificial cattle to giants, that is).
There are a ton of nice little touches in the game, too. Like in the Abandoned prison you can find along the White River as it drops into Eastmarch; without having any quests or interactive NPCs in that old prison, Bethesda managed to tell the story of what happened there via notes left there and by the skeletons you can find lying throughout the prison. Gotta give a tip of the hat to Bethesda for details like that.
