Same great game with some touch ups. Matchmaking/online play on PC is a lot more usable than the GFWL/original Steam multiplayer days, including the ability to use passwords like in the later games. Framerate is also now consistent in all areas (most notably Blighttown). Some other quality of life is also included, like being able to use multiple consumables at once if you have a stack, an extra bonfire at an important location, and covenant management from any bonfire.

All in all, it's pretty much everything you could need from a remaster of this game on modern platforms and a straight improvement over Prepare to Die edition. If you are looking to play DaS1 for the first time, this is the one to get.
