I didn't realise this wasn't the full operation volcano game I'd heard of when buying it but is seems far simpler and easier to use than the reviews of the fuller version. Saying that it plays like a full game. My 4 year old loves it and although he couldn't control much the first couple of goes he can now do about half the missions himself and he just loves it he does love anything with thunderbirds though! I have to admit to quite liking it myself, on expert level it is quite challenging with having to input map co-ordinates there is definetly plenty of room for growth and I'm sure we'll be coming back to play it for several years to come there is also a encylopedia of all things volcanic with keywords linking to other entries and images and some with soundclips too.
As they say FAB
