I just recently reinstalled a game that I've been playing off and on for years (it's very time consuming) and I thought I'd let my buddies at Destructoid in on the fun.
Progress Quest is a game where you do absolutely nothing. Well, you do have to name your character, pick your class/race, and roll your stats, but after that, nothing. The quest begins and you just use your imagination while you watch a number of progress bars crawl across the screen.
The best part, however, is the ability to take your quest for progress online and compete with others too lazy to play real MMOs for the highest level. You can even create and join guilds!
So, if you want something to stare at and feel as though you're accomplishing something when you could be doing actual work (or playing actual games, even), give Progress Quest a download! If you feel like going online, I'm on the Spoltog server and I've also created a Destructoid guild, so check it out when you have nothing better to do.
