Pros: Pretty, and highly polished graphics. Story is vastly superior to D3 in both tone and delivery.
Cons: This is D3 with a darker color palette. No offline play. Repetitive mobs, bosses, and dungeons. No feeling of progression. Most NPCs are unremarkable. Skill tree is bland, and builds are extremely limited. Combat often feels as though there is no weight, and frequently feels floaty. Gear is quickly made useless after only a few runs. Gameplay is too reliant on equipment with nothing to supplement character skill when drops are bad.
Overall: It’s not a bad game, but still doesn’t scratch the Diablo itch.
