Progress Quest is basically a dumbed down version of MMORPGs, and at the same time also considered by many to be a perfect example of a zero-player game which requires no user interaction at all once a character's starting statistics have been determined.

Six windows and their accompanying progress bars indicate the loot you've acquired, your current activity and completed quests. You can also mouse over a progress bar to reveal additional information. Players can choose to create an offline account, or take their adventures online to have their achievements saved on the ranking web page.
