When Diablo 3 got its pre-Reaper of Souls expansion patch dubbed 'loot 2.0' in 2014, it was credited with turning Blizzard’s action role-playing game around. Critics and players called loot 2.0 a big improvement on Diablo 3, with changes that sparked renewed interest from a community that had dropped off following the base game’s 2012 release. Now, 10 years later, Blizzard is aiming to repeat the trick with Diablo 4 Season 4.
