The main story picks up from the previous games but if you’re new to Diablo then a quick YouTube recap should bring you up to speed with the lore. It’s not rocket science. Just a bleak and gothic world with a lot of names that end with ‘o’ and ‘rim’, and a bit of name-dropping of angels and demons. Oh, and everyone sounds like Leonard Cohen.
You start your journey in Sanctuary, a place made by a demon named Lilith and an angel named Inarius Pretty cool? Yes. Forbidden? Very! However, things go sideways and their relationship ended sourly. Like all vengeful exes, Lilith (the daughter of Hatred) is back and she’s scheming to a point where you and a group of people known as the Horadrim must stop her.
Although I described it in toddler terms, there's a proper story here but it often falls victim to its unimaginative boss fights. Aside from two or three good boss battles, the story lacks the wow factor for its campaign bosses. Only in the Act 5 and 6 the game starts to get creative with its bosses and missions. However, after 10 hours in, you know that you have to defeat a mob of smaller enemies while dealing damage to a 20 feet tall boss. That said, the fleshed-out cutscenes and proper voice acting feed curiosity. After playing Diablo IV, I want to play the old games as well and much of that is credited to its addictive build system.
Many Diablo players skip through any and all cutscenes and conversations, and jump into the hack-and-slash bits. These mob munchers spend time increasing the damage numbers and completing every single task. If you’re one of those then it’s better to find like-minded people to play co-op with otherwise you’ll be stuck hearing words of hatred from real-life friends and not from the Daughter of Hatred.
