[Ocean] Yeah, like SC4, you can build out a region by yourself, and make all of the cities serially. There are lots of players who just want to control their own world, and they dont want anybody to interfere with it. But even those solo players are going to be participating in the flow of resources that constitute the core of the games economy  the economic landscape that theyre operating in will be shaped by the actions of other players, even if they are only playing solo. In addition, there will be regional challenges and opportunities that youll be competing against other regions for. So you can play by yourself. More social players can play with their friends and accomplish more, faster, but thats their choice.

As for custom content  think back to SC4 - first we just need to get the game out, and make everything work robustly.
