If anyone said humour has no place in a Baldur's Gate game, I question whether they have actually played any. The humour was one of the best and most memorable aspects of the games:
BG 1:
Minsc and Boo
Melicamp the chicken
Noober
The old mountaintop prophet who talks about your aura
BG 2
Minsc again
Jan Jansen
Garricks' courtship
Party banter
Edwin
There is tons more in both games.
There is humor and there is humor... and the brand of Larian's wacky, nordic insanity is not as fitting to the setting, as Bioware's more toned down goofiness was.
