IGN and GameSpy recently sat down with Diablo 3 game director director Jay Wilson, to ask him some questions about Blizzard’s upcoming sequel to the overwhelmingly popular Diablo franchise. One of the the interesting tidbits from the interview came out at the very end when Jay answered a question concerning Diablo 3’s storyline.
It seems Belial will be present in Diablo 3…
“One of the things we didn’t like about Diablo 2 was that…the story was basically the same story in each act. You showed up in the town and the townspeople said, the demon went thataway. In here, every act is different. The first act is a little bit more of a mystery, there’s this cult that has been operating in and around the rebuilt Tristram, you’re trying to find out who they are. Act two’s a little bit more of an intrigue and deception-focused story, because Belial is in there. Act three, there’s a lot more.”
So there ya have it… Belial, the Lord of Lies, is going to be a part of the upcoming Diablo sequel. (Source)
