This game, and system, are really showing their age. They are okay as either a basic introduction to wargame concepts, or a quick-play game. They do not effectively simulate battles. They are fine as games.
It serves its function perfectly - it is a great game to introduce non-wargamers to wargaming. Its beauty is that there are only small forces for each side so it is easy for new-comers to deal with a smaller-than-normal number of decisions-per-turn for this type of game.
For a quite old game this plays great. There is tension due to the victory conditions - a draw is a possibility.
This is a super game. It has elements of Backgammon in the strategy as you try to position your space ships in such a way as to restrict the movment and production of the opponent while, at the same time, trying to maximise your own production.
