This game is the best diablo game by far, if not, its on par with Diablo 2. I will try to break it down as to why this is.
Cutscenes 4.5/5 : To every Diablo player, we all know that the best part of the game is the cutscenes. This is a fact. Watching the cutscenes and having your hairs on your arms stand up and you get chills on your neck. Diablo 4 100% delivers in this.
Combat 5/5: Like previous diablos, you have always had the options available to you to mix your skill set up and change your combat style around to find the best combinations. Ive played all characters and the only one that is sort of underwhelming is the Sorc, but thats my opinion, you decide for yourself. The paragon system is beautiful. Its perfect. I dont think they could have improved this section in any other way. I hope they continue to use this settup in future Diablo games.
The game itself 5/5 : Diablo 4 has learned from 3, and has made this game into a sort of open world mini multiplayer game, which incorporates many dungeons, many events, PVP areas on the map, Collectibles, Loads of side quests and some of them are worth doing, World bosses, and a joint sort of mini dungeon called legions. It honestly offers loads more and thats why id recommend playing it because the amount of content it gives is amazing, and its worth every penny.
The only downside: They removed set items. I know. Apparently they MAY introduce them back into the game in the future, however, there is different tier items now with unqiue effects which sort of replaces it.
Diablo 4 is Easily a 9/10 or a 10/10 depending on the person playing.
