Darkstone is a Diablo clone. But there is a difference one will recognize immediately: it is in 3D. But this is not the only "improvement"--the second most important thing is probably that the player is in control of two characters. The other character is computer controlled and the player can switch between them at any time. Also, Darkstone has lots of new spells and skills. The player will be walking through huge woods, have to solve a lot of riddles and descend into deep and dark dungeons.
