Here is a bit of a review of Belter I found in Space Gamer number 27
BELTER is a game of asteroid mining in the year 2076. It is dangerous work, not only because of the hazards of the mining itself, but because of the hijackers and ruthless completion. Players must buy ships, search the asteroids for a usable mine-site, extract the ore or gas (manually or by machine), and get it to the marketplace. Competition, piracy, and changes in the market will interfere with a player’s plans. Accumulated wealth determines the victor.
The game is well-planned and nicely laid out; the map is simple and rules very easy to understand. Players have a tremendous number of options at every point in the game, provided they have the money to carry them out. BELTER is more of an economic game than a battle game, though ships and men do get to fight every so often.
The worst problem with BELTER is that it can drag out, becoming repetitive, especially if you are in a pinch for cash and can’t play actively for a while.

Sounds like a great way to develop a campaign, yeah it always sucks not having cash!
