Recently i read a steam review saying the game was good but that it dosent feel like the forgotten realms so they cant recommend this game.
personally i feel Larian have done a great job portraying the forgotten realms especially for just ACT1, some examples:

Finding the Zhentarim Hideout was pretty cool
Thayan Cellar was cool especially the Szass Tam reference
Seluns temple
Druid grove and Silvanus reference
all the little lore books you find everywhere
Some conversations - Shadowheart talking about shar and selune, goblin who was imprisoned for following the old goblin god rather than the absolute
And the Underdark - coolest place ever

What about you guys, do you feel your in the forgotten realms? if not what would you add?
