You are dwarfen veterans and recall the memory of old battles. You will disagree often, since everyone wants to be the best fighter, general etc. The only way to find out who is right is by drinking, one of the favorite activities when dwarfs have no enemies to kill.
Dwarfen Veteran is story driven. Who wins the contest can narrate the outcome. No stats, no dices, no game master. Just your vivid imagination and a lot of beer.
