The Gobbos in BG III easily have the most interesting individual character representation of any npc group in any rpg. It's quite amazing just how "alive" Goblin-Town feels. It's quite an accomplishment over rpgs of the past in my opinion. Each of the little devils has his or own traits and feels unique, it's quite amazing.
Please please please let us have Sazza as a party character. I fell in love with her immediately.
I love the goblins characterization here, it's a lot broader than in most games even when compared to say WoW's goblins they are positively well rounded in BG3 while still being recognisably goblins.
