My two boys, 5 and 7, have been playing this for just over a week, and the gameplay is varied, exiting, challenging, funny and captivating. The graphics on the Wii version are the best I have seen for this type of game with masses of different environments and textures. The game itself is a big hit.
The hardware however is something else. If the game is good, the accessories are outstanding. The portal of power is a solid well sculpted and fantastically engineered piece of kit, which is actually quite attractive in its own right! The action figures that serve as memory units are detailed, well painted and made from soft, hard-wearing plastic, unlikely to break easily. Compared to other figures such as Gormiti, their use in the game actually means they are pretty good value for money.
Yes, if you went and bought everything in one go, it would be fantastically expensive, but get the game and add extra figures as pocket money treats or rewards, and they are doubly good, a new toy, and a whole new experience in the game.
This could easily have been an exploitative, pester power money making scheme, but the creators have invested time, care and effort into making sure it is not.
