If they make a lot of money with the remaster they should and will invest it in the future. Like Diablo 4.
People need to stop living in the past. New content for outdated games does not bring back the same feeling like it did back in the days.
Better invest in new games, attracting new and more players.
I loved D2 and will play the sht out of the remaster. But it is just old and pretty boring gameplay to be honest...it's just a perfect mix of nostalgia, atmosphere and familiar content. I will drop it once they release D4 and if it is as promising as the trailer and gameplay made it look.
