I basically just use the QuickWars rules so the pacing of the game is faster and more enjoyable for the less hardcore rule-geeks I play against. We resolve questions with the 2005 rules and disputes are always solved by "what I say goes".
We used to play our own Brik wargame before we even discovered BrikWars, which is why I think we're so light on the rules now.
What we would play back then was more a game of creativity than strategy. Each player would start with lots of minifigs, and each one would get a heroic feat (guaranteed success) each turn. Very simple, no stats or die rolls. We would basically just play to see who the last man standing would be, and that particular minifig would be the winner of the day.
