Within tabletop their main advantage was their long range (longer than even LRM IIRC).
Cannot imagine how this could be implemented in Mechwarrior type games (thinking of my experience with MW 1-4) unless shooting at stationary targets or with some kind of targeting computer implemented that calculates where you have to aim if you want to hit mech x at distance y with angle z
