An interesting video about Gamification: http://www.penny-arcade.com/patv/episode/gamification The guys who do Extra Credits are generally very knowledgeable about the video game industry and this is one of the topics they talked about.

@Christophe Devriese The reason why there are better IDEs on Windows than Linux is more of a cultural thing. On Linux, it's completely normal to use a text editor (Emacs > Vim ;) ) and compile by command line. If you walk up to most Linux programmers and ask them what IDE they use, they'll start laughing. On Windows, it's incredibly difficult to use the Terminal and the system isn't designed for developing software without an IDE. IDE's are a completely Windows culture thing. And the only passable IDE that I really know of is Visual Studio, which has a very large software development team working 8 hours a day for years to develop and maintain. Very few free software projects can dedicate that much time for a tool with little demand. So the reason why there aren't any good IDEs on Linux is because there's a very small demand for them. Ask a hardcore Vim user about IDE's for Linux and they'll point you to Emacs. And many developers spend 8 hours of their day working for their company. That leaves very little time for developing applications in their free time, especially if they have a family. While working 8 hours during the day is tiring, that still doesn't stop me from wanting to reach farther in my free time to develop the software I want, using the tools that I love to use. Great post, I'm going to show the video to my friends. This is really what has kept me going with the projects I'm working on.
