I bet if I looked hard enough, I'd find the wads of paper I used to list which planets did the best deals for what goods I could obtain easily. Thinking back I can't believe how much time and effort I put into such a simple game (graphically speaking). Nowadays when I play something, which invariably has wonderfully rich graphics and gameplay, I don't give it 5 minutes before I grab a walkthrough and just play through it.
There was a lot to be said for the days before the intarwebz.
