First things first, buying and selling BP is neither easy or normal. The campaign system is a series of Opt-In rules, designed to have minimal impact on the adventuring side of the game, taking part in the Campaign side of a game is voluntary and players who don't take part should not be penalized. That means that players who do participate in the campaign side of the game should not have significantly more equipment, or better equipment, than those who don't. For that reason, selling BP to make money to buy extra gear should be discouraged.

Build Points measure a player's impact on the local economy, and represent a combination of local influence, goodwill, access to labour and materials, preferred exchange rates with other local businesses and many other aspects of the local economy. You can't just pick up a BP from one place and take it somewhere else. You can, however, use your influence and goodwill to 'cash in' a build point or two. However, that puts a strain on the local economy - so you can't do it often.

Worse still BP in different types of terrain are made up in different proportions - and that affects their monetary value. In a wilderness area, there are plenty of natural resources, but they might be hard to collect or in a dangerous location. In a rural area there are still plenty of resources, but more people about and roads make transportation easier – but you need to get permission and support your staff through the first couple of years. In an urban hex, resources get used up more quickly, land is more in demand and permission can be more difficult to get and you still need to support the development through the first couple of years. Once you are inside the town or city itself, resources need to be shipped in, competition for land is very high, and there are taxes and fees to pay. It all means that there is less cash involved the further away you are from civilization.

The table below lists various sale and purchase guidelines for when you convert between GP and BP. The left most column lists the type of hex - that should be self-explanatory. The next three columns list 'purchase prices' or how many GP you must put in to generate 1 BP in the given Hex Type. An Outsider (who has no real link to the location) will pay more than the Standard Rate, which a resident of the Hex would pay. The Preferred Rate is for those people who have been granted special rights in the area. The final column represents what you will get if you cash in a BP in any given hex.

NOTE: In The Stolen Land game Anyone who is a member of The Midmarch Chapter of the Brevic Knights gets the preferential rate in the whole of Midmarch. Any other resident of Midmarch gets the Standard Rate. Any PC who wants to get established in a different area (such as Jovvox, Mivon or Restov) should expect to pay the outsider rate.

(*) A Secondary Hex is one that is protected By a +2 (or better) defensive building in an adjoining hex.

You may always sell a building (Jetty, Inn etc) or a resource (Mule Train, Ship etc) that you own. You get the sale price per BP - although the buyer pays the purchase price - the rest is lost in gaining permission and establishing good will with trading partners (etc).

If you try and take too much cash out of an economy, it will become unstable.
