Sacred 2:Bobby Fischer
Play chess with giant pieces such as an orc and a boar. The quest for this Easter Egg allows pieces to come to life and manifest ghosts. It is called Nouveau Varguz and is given by the orc chieftain in Tharak, where it will take you to a cave just northwest of that town.
It is bugged in MP, but can be completed with the use of the last Community Patch for SP.

Congrats to all the chess players around there for their memory of chess matches. Fischer's winning move was with the Rook/Turm and Fischer died in January 2008, probably around the time quests were coded.
