Since so many people want to say that D2R is not a remaster and that the game needs so many changes like D3 here is what the D2R main page says right as you scroll down.
A Timeless Classic, Resurrected
"Diablo® II: Resurrected™ is a remastered version of the quintessential action RPG Diablo® II."
This is one of the first things you see on the Diablo 2 Resurrected main page
Furthermore,
"Classic gameplay—the same Diablo II you know and love, preserved."
There are 2 things here I would like to address from this quote
Classic gameplay:
This suggests that the game will be the same as the classic and that the same game mechanics will be present in the gameplay. I believe that this game will truly be the best it can be with the classic game mechanics.
Preserved: The developers have stated that their main focus on D2R is to preserve the feel and experience that players had in the original and to not stray from that in any big way. They have spent time looking at the original Diablo game and the original Diablo 2 game to see what was adapted from both games at the time to make diablo 2. They have paid attention to the finest of detail and are still working to make this game as close to the original as they possibly can.
I do not believe that this classic remaster needs to have changes that D3 or PoE players want. This is in my opinion, with evidence to support, a game made in appreciation of what really made the diablo franchise as popular as it is today through diablo 2. All of its amazing, memorable, dark, gritty, and even flawed ways have stood as the pinnacle of the diablo franchise. It may have not been a perfect game but I would make the argument that playing tetris with your inventory, picking up every potion and scroll, trying to stay away from hostile players, grab the loot you earned faster than those players, and trying to preserve space for new items with an inventory full of charms is part of what made this game so memorable and challenging and enjoyable.
Diablo 2 is not a game that will hold your hand and give you unlimited gold, unlimited gems, unlimited space, overpowered damage bonuses, and the ability to switch every decision you have made with your gear and skills at will.
Diablo 2 Resurrected will have a bigger stash and the ability to toggle Auto-gold but those are not changes that really change the experience at all. Those are changes that are more convenient but not at all harmful to the game. I am in favor of these
I hope to see Diablo 2 Resurrected played almost the exact same way as the original. People can complain about the original as much as they want and keep wanting change but I believe that if they had played the original the way they are intending the new game to be they wouldn’t remember it and love it as much as we all do.
