If Thal is doing mostly data edits first, then modifying units and buildings, policies and terrain to some extent, tech reveals, and some leaders (unique units/buildings) or wonders is pretty easy (and probably wouldn't require updates to CivUp in most cases). Some, but not all, of that doesn't appear to have changed very much at all in BNW, which suggests a need for some modification without much debate. There's some obvious issues with trade routes and ideologies and specialists that may be a call for immediate discussion. Completely new motions. If integrating those kinds of changes with more complicated UI changes will take a while, I'd say we need a strategy for dealing with the UI and lua changes. I'd suggest we break up CivUp into segments so it can be done in the background while the easy stuff gets laid out (and can be verified as working before any bugs appear). The alternative is waiting for different bits to get cleaned up and tested by one person. Might be safer that way, but burning out Thal is not very fun.
