Progress Quest: easily the best game to play when you don't have time to play games. Progress Quest is a game that is played either single player or online as an MMORPG. The game practically plays itself, which is great for times when you have to be AFK, but need to continue through the quests in the game. It takes the hard parts of MMORPGs, such as leveling up and repetitive and mundane attacking of creatures that is involved in that.
How to Install
Open a terminal and type:
sudo apt-get install pq
Now it will be installed and you can run it from the Games menu under Applications.
The game will walk you through the initial part of the game, such as choosing the type of character you are and initial stats, and whether your game is played online or offline. After that, it's game on. Just watch the magic go.
Now, obviously, if you haven't figured it out, this game isn't really a game at all, but at best a parody of the MMORPG market of games like Everquest and World of Warcraft. In addition to being a parody of the game, it has also become a parody of the entire genre and the players of the community. On the Progress Quest web site, there are forums that you would find similar to the ones at the big game sites. There are also two strategy guides for the game up on Gamefaqs, which is saying a lot for a game that isn't really a game.
If you're looking for something that's somewhat interesting, give PQ a shot. There's not a lot going on, but if you leave it run for long periods of a time, it gives you something to check on every time you get onto your system. I give it 4/5 overall.
