Maybe you should play DS, and then you will see that it is not a diablo clone.
I liked Dungeon Siege, but I don't think you'll get very far arguing that it WASN'T a dungeon crawl (Diablo clone).
Read my sig, I'm here for a few hours, and I already had enough discussing that LOL. Why do you guys consider hack & slash RPGs controlled with the mouse diablo clones? Dungeon Siege is unique in many ways.
Because it's easy to type and everyone knows what Diablo is and how it played.
And yet Dungeon Siege didn't play anything like Diablo, so typing it that way does seem a bit odd.
IE to my mind Diablo is about preset classes with skill trees and randomly generated levels in a game that only has multiple characters in multiplayer
Dungeon Siege had no classes and one could pick from any skill in the first one and it had a predefined map and has a party based gameplay.
About all they had in common was both having action based gameplay. Because if being a "dungeon crawl" makes you a clone of Diablo then Diablo is a clone of every "dungeon crawl" that came before it (which it isn't).
