This is objectively wrong. If Diablo 2 is a 10 Diablo 3 is a 8 at best. Diablo 3 has fun elements and killing monsters is very satisfying but the goofy voice acting, the story, the music, the items, the levels and the skill trees are no where near anything in D2.
Here's D3. Hey, here's a skill. You like that skill? Okay well instead of being able to increase it's damage we'll let you add fire, electricity, frost or some other garbage to it. Want to up the damage, find a higher damage weapon as a sorcerer. How idiotic. I enjoy many parts of Diablo 3. Diablo 3 is a great game, it's just not a great Diablo game. The atmosphere, the music, the skill tree, the danger. It's all wrong. In old games when you died it was terrifying. All your loot dropped on the ground! It was a very intense experience. Diablo 3 is all about spamming. If you die who cares. Added depth of managing health and mana? Ehhh we'll just throw some orbs on the ground. Keep spamming and have fun picking those up.
Diablo 2 > Diablo 1 >>>>>>>>>>>>>>>>>>>>>Diablo 3
