Simcity on wii or DS collaborative project

My grade 5/6 classroom are about to begin a unit of work relating to our Humanities curriculum that will use Simcity creator for the students to build their own cities through time. Are there any other classes who would be willing to use Simcity creator (wii or Ds) as aprt of a collaborative project?
At the moment I am thinking about a wiki based project where students or teams can input their city information as it grows, also a tips and hints section based on how to build a thriving city. The time the students will spend on their Simcity World would only be about 30 - 60minutes per week as part of the project.
