This has one feature that needs to be emphasised - it is for more than one player and cannot really be used along! If my child was using a computer for long periods (as I do now!) I would prefer him/her to be using a program like this than to be at the keyboard alone simply for the interaction with a human rather than a machine opponent. This game can accommodate up to nine players and is really a rather souped-up board game. The purpose is to become rich by mining, transporting and trading rare ores from one planet to another. There are plenty of changing situations to try to take care of and profit from.
What part of the program depends on luck and what on skill is hard to determine, but it is fun. The only criticism I would make is that the screens could have been more colourful and better presented (all Mode 7) and that some graphics would have been nice.
But what can you expect from a game which can hold the actions of nine players in its memory?
