It seems like a lot of people want me to justify why the Wii should be in its own generation rather than be included in the same generation as the PS3 and Xbox 360.
A large portion of this organization was influenced by discussions on the evolution of value systems within society; in most of these discussions value systems end up being discussed in how they influence how an individual or group sees the world through the filter of their values, as well as how an individual or group is seen through the filter of their values and the values of people who hold a different value system. One example of a discussion would be on how an imperialist would be seen by (and see) an environmentalist.
Part of the reason I started thinking about it in this way was how the interaction between HD-Gamers and Wii Gamers was very similar to how people of different (but closely related) value systems relate to each other. The thought I started to have was that the value systems that built these systems, and of the gamers who choose these systems, are very different. You can see these value changes in how the similar features between the two systems are actually very different.
Consider online gaming, all three systems allow for online game play and yet the PS3 and Xbox 360 have a very different approach than Nintendo has with the Wii. The HD consoles have adopted the PC model of online gameplay where there is a focus on an individual (using a personal headset) to communicate with a 'stranger' in a highly competitive environment (leaderboards, achievements, etc.) with little consideration for an individuals feelings; in contrast the Wii is moving towards a system where a group (using a public microphone) communicates with their friends (friend codes) in a friendly environment.
