ESO shows a lot of the background lore stuff that the mainline games ignore, and generally does a better job showing off the setting than they do. Sadly nothing really captures how weird and fucked up the Elder Scrolls setting is, like the world as described in the in-universe books is more like the setting The Witcher series portrays than what the TES games themselves do in terms of idiosyncratic creatures and magic and what absolute pieces of shit everyone in the setting is.
