By use of the various tools of the system, and using them well, everyone other than the GM was having fun, and they started doing likewise; I used my character to do "let's You and Him Fight," true, but I did so to enable them to actually do well the things their character sheet implied they should be doing .
Okay, just so you know, that doesn't sound like "I broke the campaign." That sounds like, "the GM didn't realize he was softballing us". Do you understand the difference, and why I would react to one and not the other?
And I've made it clear previously that I think Fate is neither trad nor truly storygame, but in the murky space between them.
You keep saying that, and I don't understand why. The word "storygame" has not been uttered by me in this conversation. I don't use that term - I think it is so ill-defined that it actually gets in the way of understanding, rather than enhancing it. I have no dog in the fight of what bin you choose to put the rules into. If you think I am arguing this point with you, please rest assured I am not - I do not care.
