The game is essentially Diablo 2 just updated to work on newer PCs and improved graphics etc.
I am surprised by some ratings and super thankful that Blizzard didn't ruin this game with "modernizing" it, it's just a remaster, otherwise this game would be ruined as well as they did with everything they touched. There's Diablo 3 and 4 for a reason for people that want more consolized / simplified / arcadeish games.
This is not perfect, but to be honest in today's world when companies sink hundreds of millions to make totally crap games I'm thankful for D2 to exist and continue to run on our PCs. We have less and less games with identity and more generic garbage that looks and plays all the same, with the same graphical effects and art style.
