I'm currently re-playing Diablo 2 for the first time in years (decades?) right now. Got a fix for ultrawide and a preset that smooths the textures. Game still looks great visually and holds up really well. It's obviously still a 20 year old game, but still a massive amount of fun.
If they can bring something like this into the modern era with redone sprites / textures as well as updated cutscenes, it could help bring appreciation to the game (and the genre itself) to a whole new generation of players that weren't alive when it released.
