I don't understand why this has achievements from what I am reading all it is is new blades that you can use during the game. This is something I do not want to spend my money on I don't care if it was a monkey ass as the blade I don't want to spend my money on it but yet I went from an S-rank to 56% complete. I am not a fan of the nickle and dime you DLC this very much reminds me of the infamous "Horse armor".
Are there other games out there that have this same kind of practice? It doesn't need to include achievements, I just bring that up because as a person who like to try and complete a game as much as I can things like this drop my stats :(. I love stats if it isn't your thing I understand.
