I mean, he was a big part of the early original BB, too, but then you had to get rid of him to continue the story.
Except there was no story. DS got rid of Eric because his Patrons didn't like him. It was not something he had planned, nor was the whole porn story line. He just started making it up as he went along, which is why there were so many abbandonned events (Alice's spanking, Lisa's anal, Kira, the pills for Eric and so on).
I don't get why people don't like Eric so much. Yes, he's an asshole, yes, he's terrible, yes, he's blah blah blah, I get it. Me, I like him because I'll have the opportunity to hit him where it hurts. He's so confident in his womanizing abilities that he'll never see it coming when Max steals the girls away from him and fucks them behind his back. You guys be happy with giving those pills that kill his boner. Me on the other hand, I'll settle for nothing less than fucking Ann while he's crying in the bathroom.
