Heroes Unlimited - Attributes & Rolling

Wanted to go over the 8 attributes that standard through out all Palladium games, the method of rolling, exceptional attributes and what the differences are between Revised vs 2e along the way. I always find rolling stats to be a fun and surprising experience. Sometimes you roll so good and you are like, my character will be a bad ass, and other times you are like, "meh" and need to roll again. How do you allow the rolls? 3d6 straight down the line? or 3d6 and place as you please?
