Summary: I had earth 2150 years ago and it left off with a hint of a new game earth 2160. This is the exact same game renamed. I thought maybe it started at the begining of 2150 and would go on to other levels and boards givivg players a chance to get use to the game before moving on-not so, a waste of my money. You can get an old copy of 2150 on ebay for a lot less. Don't get me wrong, if you never played Earth it's not bad, I thought it was new not renamed.
