If you are lucky enough to be at Essen/Spiel this year, and you are strong enough to battle your way through 150,000 people... you can demo Quarriors: Quest of the Qladiator at the WizKids/Neca booth (5-34) well before its release next month.
WizKids is in Hall 5 (Halle 5 for locals), in-between Queen Games, Topps and Städtisches Spielezentrum Herne.

Unfortunately, I will not be there this year but maybe next year? Some cool things happening for me outside of direct game design, which we'll be announcing next week. Can't wait!
