A game option for free play would have to spawn a certain number of alates in order to win. Each alate would be very expensive, and the price would go up after the first alate. These alates would then eventually crawl out of the nest and fly off (like a lady bird beetle). I feel this would give a more simulation aspect to the game that many players want to see, without needing any massive changes to the game. Also it would be a fun way to test survival skills with attack waves on.
