One of the most amusing and at times frustrating games I ever played was a campaign inspired by the Napoleonic Wars. The French were Gnomes who were extremely bad French stereotypes armed with muskets and liable to flee if their unit got attacked by three volleys OR their officer and/or standard bearer got sniped. Several parlays included awful french accents on the part of the DM and more than one encounter outright avoided by the PCs hiring a bunch of whores to distract or appease the frognomes, complete their objective and move on.
