This is a great game. Don't get me wrong though. I work part time and the two achievements that require playing the game straight through the Apollo program without quitting the game just once is a little extreme such as getting the one giant leap achievement. It should be that a save state should preserve all of the stages of the game so that you can continue to resume your mission. Now I'm not bashing this achievement and its a great triumph. Also When can we expect the Cesium moon elevation and the Reentry autopilot working for the Apollo program. Another thing. see if you can add the pause button in important events such as reentry and burns. Thanks
