I used to play in your All Stars group Jon (don't recall which character. Lionheart? Some vampire type guy?) and currently run a game using the Golden Heroes game from way back. Also (trying!) to write and finish a diceless game based on the out of print Marvel Universe Game. Basically, it's resource management based. Your character can do certain stuff automatically, and add energy points from a pool for extra effort.
e.g. Wonder Man (the original version) tries to lift a truck. His Strength of 5 allows him to lift 1000lbs per point, so a total of 5,000lbs. For every extra point of energy he adds 1,000lbs to his lifting weight. If the truck weighs 7,000lbs, an extra 2-3 points of energy will do the job.
Obviously characters don't have an unlimited energy pool and combat sucks it away like nobodies business.
Am determined to finish it, but it's still in the writing stage, and of secondary importance to my long running Play By Forum game which has had the superheroes start in modern times, be hunted by the authorities, civil war style, then go into the past to set history right when bad guys from the future win WWII for the Nazis. Throw in aliens, zombies, a side trip to a mythical/mystical land and it's a real hotch potch, something for everyone. (I hope!)
Cheers, Paul
