I only needed 1 - hoard of disposable peons to slaughter. It's always fun, and some BBEG is always in the thick of it, usually with enough wits to trick the PCs several times before getting whacked.
BTW, I abhor the 'meeting in a bar' crap. I have never liked a DM that used it, and now it's a tell-tale sign of a DM that doesn't know how to pull a party together.
