It varies. If I die, it doesn't matter. Hell, I'm suicidal, most times. But if the fun gets killed? The shit hits the fan. First, it's perma-scowl-o vision. Then, it's under-breath cursing. Then, it's yelling. Then, it's off to the kitchen to fix a drink, and rant about everything that's wrong with the game I was playing.
It doesn't matter if I win or lose, kill or die, massacre, or just scrape by; if it's fun, I give not a shite. If the fun dies, so does everyone else. If that doesn't work, then go by the anger chart posted above, for my reactions. End of line.
