Having a save capability "saves" this game from the scrap heap for me. Without a save capability I had to have 2 to 3 hours free to play or accept start it knowing that if I did well I wouldn't have time to get to the final stages. At this point it takes me that long to do the micromanagement I need to get through it. Not having a save made it pretty much impractical to play on an airplane or play during lunchtime. How about when you are in the middle of a game and the wife says it is time to come to bed. So I played the beta a few times and then moved on. I just decided to come back and check if this vital feature (for me) had been added and was pleasantly surprised.
So thanks to the developers for listening and making this great game playable!
