Great base game! But as far as the "remaster" changes go, they added foliage and animations to Firelink Shrine (nice!) and did some modern FromSoft tweaks like multiplayer passwords. Past that it's all the original game's assets run through an engine with botched material lighting. Metals are all dull, stone and living things look more wet than intended, and strangely enough they decided the bonfire looked too ethereal and abstract so they put normal fire there instead. The original Dark Souls didn't look like this! If you can manage, please try to get a hold of PtDE or use a fanmade texture overhaul mod.
