only one word can describe this game Addictive
You can play as The Russians or The Americans in the space race it trys to be as histroical as it can be like using the same CM like the Apollo CM and even Astronaut's.
Once you understand the game is highly addictive but the A.I does the same thing depending on what you did 2 turns ago and the events don't have varity what so ever.
Once you have completed this game you can finnaly but your feet on your desk or whatever you have around you and relax but this game is highly addictive and as Micheal J Fox (i think it is the guy from Back to the future) said in a episode of scrubs "This toliets got my number" but in this case "This Game has my number".
