Also, if you want some food for thought for making up your own tactical decision games, you can search the Google news page for any kind of bad situation you want to. Putting in "fight + wound" usually manages to come up with a bunch of crazy stuff, and all stuff that actually happened to people within the last couple days. Like, wrasslin in the street ... thump, fatally run over by a car. Or, kid crashes his car in the front yard and stumbles to the house for assistance ... just escaped from the loony bin and goes apeshit with a kife as soon as he gets in the front door. Lots of interviews with survivors, "It was all so confusing, I was kicking the guys ass when all of a sudden somebody shot me!" And all those accidental fatalities, a poke in the nose, a cranial breakfall and the last man standing is standing in court on a homicide charge.
