Very Confused on why I should play BONELAB

I've always been confused as to why I should ever play this game, I LOVE Blade and sourcery for the immersion I feel swinging swords and killing enemies, but with bone lab, everything feels very goofy and not serious, I understand that's the "point" and that this game is meant to be moddable but it doesn't seem like the building blocks of this game allow for modders to make super in-depth campaigns or intense gunfights. I just can't find an inclination to why I should play this game, which is weird cause this would be the exact kind of game I would normally love.
