Do not bother. Game is EXTREMELY pay to win. Every single "event" is just spend money or items to get points. So the difference between whales and non-spenders in this game is hilariously out of balance. Most of the game modes are very buggy. Sometimes abilities just don't even work. And there isn't much to do once your building slows down to 2 WEEKS between buildings, and days waiting for research to complete. STAY AWAY. Edit: Dev reply is exactly the problem. "Need more time with it" = boring
