Curious, what development methodology does Gree subscribe to? Like Agile/Scrum, or Kanban etc.

Can you guys provide a list of explanations on how all the different stats work?
I read the other day that when you attack someone it is your attack stats against their building stats. How is building defense calculated?

How does someone with 100m stats less than their opponent win an attack in WD? So many questions about this type of stuff, I can't even think of them right now...
