Hi, I been playing for a couple of months now and I have yet to notice any difference. I still do it though because I read somewhere that it's supposed to help them be smarter and therefore be able to discover more things (if you haven't already discovered everything yet) and be more efficient as adults if you have. I currently have two villages running completely on their own now. I just check in every once in a while out of curiousity. I have just bought the second game and am trying to figure it out.

And yes, these games are addictive, LOL!
