I, uh, hate to say this...but my suggestion of Vegas was pulled completely out of my ass.  I just wanted a third city to go with Miami and Bucharest, and Vegas was the first one that popped into my head.  I never expected anyone to vote for it.<br/><br/>There is another option - have the main story set in Miami, and maybe have a few of the characters (read, non-Wizard/Sorcerer) go to Vegas for a subplot or something.
