Alexis has a new venture: comics. This one perfectly captures what players like to do with their time in the game world.
Goat took your pouch? Burn it. Hireling fucked up? Fire him. Those guys shot at me? Shoot back!
When the party is wronged, they like to punish people! They'll want to get those fuckers!
When in doubt, the DM can always make a fight personal, and then capitalize on that emotion of indignance. It will drive players to jump into action.
Just be careful not to stir it up all the time. Any emotion will get stale if it's overused.
