I am curious how most GMs here prefer to handle large combats with unimportant mooks. Do you have the players roll out every round and attack against 40 guys or merely a few in the begining and then gloss over the rest of the battle? I have found that the second option works best for me ... it allows the players to fulfill their desire for battle and throws them into danger for a short time, but prevents the engagement from becoming tedious. If there is a real villain/dangerous figure in the mix, I run the first few fights, then the last couple before he jumps in, giving a sense of continuity without taking up hours of game play.
How do you prefer to address combat and why?
