i feel like this doesnt get mentioned alot here, but there is a mod out there for Dark Souls 1 thats called "Daughters of Ash" and its the best thing out there you probably didnt know about.
It feels like a Directors Cut, the whole progression path trough the levels is different so it doesnt feel old, theres new Bosses, redesigned areas and even new scripts AND Quests, including hidden ones.
Everyone here who owns the PC Version should give this a go, its like playing your favourite game for the first time again.
