Baldur's Gate 3 director says Larian had "all the freedom we needed" to make the D&D RPG but adapting the tabletop format provided its own "limitations"

Wizards of the Coast was apparently not precious with its legendary tabletop game
No one from the studio explains what these limitations are, but players in the comments believe they include the restricted level-ups.
I remember reading that enough spells past 6th level are difficult to implement because of duration or scale. A couple high level spells got nerfed to fit the game- Hope (and Shart, i think) can use a modified Wish spell.
