The Scum Villain's Self-Saving System question

On the third volume of svsss and even tho I am liking what I am reading I can't help but feel underwhelmed. I have read tgcf and mdzs before so I was expecting something similar and the lore as vast as those two in this one too. But I am a little disappointed. I will still keep a flexible mindset until I actually finish the books and I hope this one goes down as one of my favourites because the other two are hard tens for me. I enjoyed them so much I couldn't put the books down!!
