About Wizardry II: The Knight of Diamonds

Wizardry II was infamous for virtually requiring players to import a party of 13th level or higher from the first Wizardy game to stand a chance of making any progress (said so on the box). Later versions were updated with a pre-made 13th level party to overcome this problem. However, the Commodore 128 version never received such an update, helping to make this version it obscure among the obscure of the obscure.

Certainly this failed marketing ploy was influential in the industry, as nearly all later sequel within the RPG genre would tac-on a bunch of experience points to newly created characters and had pre-made parties in addition to having character importing.
