You could probably just have one person maintaining a central site, linking to 29 different sites. That would be easier to maintain. But as has already been discussed, a lot of people seem to be losing interest in Franchise sites, mainly because they do not - and cannot - feature as much interactivity as a forum like this one. That makes it harder for the visitors to get involved and take an interest in your Franchise.
Not that I think Franchise sites are a terrible idea. I admire the passion and effort that goes into them, I used to maintain a season page when I ran the NBA Live Domain, but I quickly found out that users were much more interested in the patches, news, hints and tips, and so forth that were featured elsewhere on the NLD.
If you want to go ahead and do this, by all means see if you can get a group of people together to accomplish it, but keep in mind the amount of work that must go into Franchise sites, and the number of sites that have become defunct (such as skiptomylou's) due to the declining popularity of Franchise sites in general. If you do go ahead with it, I strongly suggest that you consider my idea of having a central site linking to other sites rather than having them all stored in the same webspace.
Best of luck with it.
