Yes, the realm of the Diablo franchise still has the capacity for more story and plot, but let's be honest to ourselves, who really played the Diablo series for the story? We all played for the action-RPG genre experience that the Diablo games defined and honed: the compulsive click-click-click hack'n'slash towards that one more level, and the addicting hunt and hoarding for better items. That said, a game need not have the title "Diablo" to deliver that kind of experience. If you just want more of that formula, no need to wait for Diablo 3. There are well rated and praised Diablo clones, to satisfy those who want more of "Diablo". Some games such as
Divine Divinity, Dungeon Seige
1&
2, and
Fate.
Frankly, I'm just waiting for Oblivion, which looks to be the next big thing. It's going to be out on Monday.
