The Portal is closed… for now
WizKids Games announces the just released Mage Knight Board Game is sold out
Amass an army of followers, learn new skills and spells, rule through respect or fear—these are the choices of the Mage Knight. The portal has opened and many of you have stepped through. So many, in fact, that the first print run of the Mage Knight Board Game— intended to fill projected sales for the entire year— has sold out in the first month of release. WizKids Games wishes to congratulate game designer Vlaada Chvátil on his creation of the Mage Knight Board Game which is being enjoyed and applauded worldwide by fans of this epic fantasy game.
Due to this overwhelming response, a second production run of the game is assured. We are also excited to announce plans to release the game in German, Czech and other languages as details are finalized. Please check back to wizkidsgames.com or your distributor for updates on language plans and availability of reprints.
Please note that there are very limited supplies remaining for American retailers through Alliance Game Distributors or Diamond Comic Distributors – contact your sales representatives for order information. International retailers may find small amounts available via their local distributors
