That sounds like a great game!
One day if I have a good solid two weeks or so that I don't have to work or have any other commitments, I'd like to play continously and have a super long game. I'd buy enough food and drinks to Last a couple of weeks and I won't leave the house or answer the phone. I'll just play non-stop until I've completely conquered the galaxy and totally built everything up.
I need to play continuously because if I save and not play for a few days and come back, I don't feel like continuing and I have to start a new game.
