Bizarrely, I cannot say, because whichever version I have ever used, myself and my fellow players have modified according to our needs, including adapting for campaign play, using old siege rules, adopting fan-made or home-made army lists, etc and what not.
Like you said, for me it is all about story. Not, however, just making a story up, rather creating a ruleset that allows a campaign story to unfold, giving real scope for creativity and strategy, alliances and politics, for the players and the GM.
I am also with you on being against 'power' gamers, in the sense of min-maxing and creating tournament/army list legal lists taking advantage of every legal twist and turn, every accidental (but printed and RAW) rule. I get what they are doing, but their version of play is far removed from mine. They want to win, while I want to be creative and lose myself in a fantasy world, I want to have fun with all the other aspects of the hobby beyond tabletop official scenarios.
Which is indeed what I should be getting on with now with this bit of free time today!
