Are people genuinely trying to compare the humor of Baldur's Gate and/or Baldur's Gate 2 to that of Larian's zanier attempt? Holy cow.
Yes, because humour in Bg and Bg2 for me was cringy and off-puting.
This is a matter of degrees: one of them (i.e., the original saga) is a firecracker and the other (i.e., Larian's project) is a main-sequence star. Also, I don't relish saying this, but, the writing/pacing in the Baldur's Gate series was head and shoulders above everything Larian has produced thus far; I never walked away from either title (or their expansions) feeling that the experience was generally goofy.
