Clickquest
Clickquest is an online "MMO" dreamed up by Alex. It is completely text-based and it's only real feature is a chatbox and user colors. Gameplay is limited to One Click = One EXP, and each level up takes 10 times the clicks as the last. The max level is 100 (although a promised expansion will add 10 more levels!), which would take over six million clicks at this rate.
LRR Fan Fugiman did indeed take up the challenge of making the game a reality. The first release at http://clickquest.x10.mx/ has already garnered over 200 users and 1.5 million clicks (as of Aug. 25 '10). Fellow LRR Fan Nmaster64 purchased http://www.clickquest.net/ and is assisting with server administration. Fugiman is preparing to release a new and more stable version of the game soon.
Origin
ClickQuest originated in Crapshots episode 45, The Grinder, as an absurd metaphor for games like World of Warcraft and how pointless they are at their core.
