So apparently I was watching the replay of my last game, and I noticed the AI was purchasing the launch for the off-world market without having any of the resources. I watched it do this about a dozen or so times. Now I realize that you can just purchase the resources outright, and ship them off world; however, it still seemed a little "wrong" in terms of gameplay. Maybe I was just disappointed that I didn't think of doing that first? When you read the text of the description to launch the rocket, it makes it sound like you must have the hundred units in your stockpile, or at least that was the intent.
