Consider what I am going to say just my humble personal opinion, so please NO torches
Many people are asking for the possibility to play the game directly on hardcore difficulty, being afraid that if the game is going to be to easy they are going to lose the "first time experience".
As an old gamer I am familiarized we the "gaming rage" like I am sure most of you are. Going on hardcore difficulty from the beginning in a new game can increase the possibility of dying in the same place over and over again and I do not know you, but for me it is not fun at all.
I believe we should trust the producer, which after many testing(God know it is a lot of testing) will take the right decision.
