Well since I'm looking through the forum I might as well make a few suggestions:
1. A new state in England? England doesn't have states it does have provinces/regions. Unless something really drastic happened in this fictional future time line I think that they will keep calling them provinces/regions.
2. Instead of just England I would make a board for all of Europe and give each country it own fictional city but that's up to you guys. This also goes for Japan, which could just as well be east Asia making it include China.
3. More information on what happened in the past of this alternate time line. This will probably be added even if I don't mention it but I personally think the history of a setting is important since some people may want to reference events of the past in their character histories.
