Die Gilde is actually one of the more successful german game titles. I enjoyed both PC predecessors especially in multiplayer. On the PC it was an economy simulation with some RPG elements set in the middle ages. All about starting your own medieval crafts workshop, producing stuff, selling stuff, buying stuff, trying to hinder your competitors by torching their businesses down, finding a wife and producing offspring to continue your legacy and eventually run for town mayor. Dunno how it will look like on the DS but except for the horrendous bugs the PC titles were actually really good.
Trust me, simulation fans in germany (like me) almost wet themselves with joy and nostalgia upon reading names like Die Fugger, Patrizier or Die Gilde. Stands for quality medieval themed economy sims over here so I'll definitely try this one out.
