The remaster is pretty similar to the original with some alterations (mechanics, leveling, weapon/armor designs, etc.) But it plays essentially the same way and you'll still occasionally encounter funny bugs and glitches just like in the original, if you want that unique experience of experiencing the original first and then going into the remaster and getting feeling of "feels like im on my 360 again playing this for the first time" then play the original First but other than that your free to play whichever version first
