The premium looks amazing but its extra features could be taken advantage of better with more code. The extra movement of the Slimer mech on the premium is cool but is useless as there are no rules to take advantage of that extra movement. The Slimer mech on the premium should work like the crane toy in Batman, move to one spot and then not move until a player hits its, then move to the next spot, etc. Instead the Slimer mech on the premium just randomly moves to spots...Same goes for the Ecto Goggles, awesome feature but there's only a few images for it.
As a whole package I think the premium still has a lot going for it, much more then other premiums. I just hope that the code is developed more for the game.
