Today I feel like talking about another game, Minecraft. Minecraft is a simple sandbox game. It is not the most impressive looking game but what it does best is allow for user generated content to flourish. It sets simple perimeters that allow users to experiment similar to playing with lego. Lego have particular methods for construction however it does not limit what could be created. Minecraft places an emphasis on the power of process. Many people actually enjoy the game for the process of creating something rather than the finished product. It goes with the whole "it's not about the destination, it's about the journey." One could argue the game serves as an educational tool to understanding the importance of the process.
The game relies on the users to continuously generate content. The focuses on the interaction between the user's experience and the content. In design, user interaction with content is important. It allows the user to become invested and connected with what you produce. Minecraft is not the only example of good user interaction. Facebook and Twitter rely on the user to generate their content, without the user none of these could exist. I could write at length on this topic but it will leave it at that.
