A roll is a roll is a roll. I don't care what they do with the dice before they toss them, as long as they don't try to play with them after they leave my opponent's hand. Unless the dice are loaded, there is absolutely no way they can affect the outcome.
This is so wrong, it is scary. I would love to play craps with you ... anytime ... for any amount of money. I, as well as others I know, have been barred from playing in casinos in Las Vegas specifically because of our ability to consistently control the dice.
It is one of the reasons that virtually all new craps tables in Vegas in the past 5-10 years have "cones" across all of their lower walls, and you are forced to hit those walls, or get a bad roll called by the box.
Now, I have made no attempt what so ever to control the dice included within the X-Wing game, but I am pretty confident that given the time and energy to do so, I could certainly control the outcome of rolls. If nothing else, I could probably use the slide method to great effect.
