Re: Bret Hart WCW - How would you book him?
I would have debuted him the night after Starrcade. Have him stare toe to toe with Sting as Nitro went off the air. And slowly built to a Sting/Hart Starrcade 1998 match. You could have done a story line where he tries to jump ahead of the pack and challenge Sting directly but several other guys demand he "pay his dues" in WCW first, sort of start it out as a potential face vs face match and slowly turn Bret heel as he claims WCW is just like WWF, they are trying to hold him down, screw him over and show favoritism to other guys.
I certainly would have had him finish off the nWo in matches against Hall and then Nash and finally the big match with Hogan which leads into his Sting match.
