You can not claim this city because you do not own some of the content used to create it

And it doesn't even tell you about the free content download that you can do (for a limited time only)

I think you should be able to claim a city just not power on the buildings that are advanced content--that would be so cool--then you could know which packs to buy--or just bulldoze them and then actually use the city that's abandoned and fix it up...become the city janitor--or have a ton of people cooperate on an abandoned region

Right now there are so many versions of sim city that trying to get 2 people with the exact same version is nigh impossible...I know I won't even bother upgrading to deluxe because I won't get the special park and still can't collaborate with my deluxe friends--and I don't care about the french cities, I just want to be able to swap ordinary cities with other folks who have a slightly different of the 52 versions of the game
