Unless you have no soul, Zack and Wiki:Quest for Barbaros’ Treasure remains one of the Wiis most endearing and engaging exclusive titles. However, its charming art style, solid gameplay and fantastic controls werent enough to save it at retail and it sold poorly. Many feared we had seen the end for our treasure-obsessed friends, but a spokesperson from Capcom has stated that the adventurous pair remain close to the developers hearts and may appear in some form or fashion in future Capcom titles. More inside Well, you know, Zack and WikiAnother one in a long line of very highly rated Capcom games that unfortunately did not sell very well. We can take a part of the blame on ourselves by having it star a shirtless boy pirate. That is actually a personal favorite of a lot of people in Capcom, so dont be surprised if you see it again but we have nothing in the works at the moment. – Capcom Product Manager Colin Ferris
