Pricing will be key, Skylanders was a huge success but as we have all seen recently the shelves are full of figures that no one wants or can afford or both. Disney infinity flooded the shelves as well but the demand was not met. (Now the same with the inferior Mario Party versions of the Amiibo)
Hopefully the lego brand will be strong enough to not suffer the same fate as Skylanders and Infinity. Hopefully the gameplay will be good enough to bring people back and the models available will be strong enough on their own to also sell to those with no interest in the game.
Game itself should be good, especially if travellers tales are involved, I have enjoyed every lego game they have made (only not played Hobbit, as it only runs through the first two movies!)
