Baldur's Gate 2 starts already on the epic note in the intro, by establishing you as a son of a literal god. God of Murder on top of that. And the Hero of Baldur's Gate. Then you fight for a control over a city (more or less), break out from the mage-prison for the strongest known mages, see/fight creatures from other planes (the Githyanki), go through the Underdark, fight dragons along the way...
And BG3 doesn't start epic? Mindflayer spelljammer ship fighting dragon riders army is prety epic IMO.
Anyway, what part of Faerun the chapter 1 happens?
Would be amazing if we can see a little of Thay on BG3
