So after reading through the interview carefully and twice over, I'm just too confident there's NO WAY this game will disappoint the core fans.
Could I crop a paragraph from the EDGE magazine scans and post it here without getting modded? Because it'll really help my post. But basically - the new directors stressed twice that the game's core mechanics will be used as a foundation and built up from, basically what you'd expect in any typical sequel. In two different sections they specifically say that the game will put player in a position where the environment must be inspected, meanings must be deciphered, for the player to manage the challenge.
YEP.
The only truly discomforting news I saw was they also said that the starting areas will be more welcoming and then later on the game gets really Dark Souls'y on you. But then they made it up with this new morality based executioner system. Sounds awesome as fuck.
As for the lore, all they mean is they are going to make it less cryptic. You can still easily miss stuff about the lore if you don't go out of your way to learn all about it. Its not all cutscenes and dialogues.
