I'm considering getting the corebook, but first I would like to know how feasible would it be to use it to create a campaign after the Unification War. I know Red takes place right after the 4th Corpo War and its Night City is still part of NoCal, but I like the idea of instancing a campaign on an independent NC.
Does the core book allow a campaign like that? Or at least does it provide tools to create something like that?
More specifically, I would like to know whether the gameplay rules and assets can be used to create campaigns that happen later than "The time of the Red". My concern is that the gameplay and rules are restricted to 2045, and couldn't be used on a 2071 setting.
