<p>In a dynamic pre-firearms world with many small states and contested regions, trade is not going to be straightforward. Not only will different routes have different physical characteristics - more or less mountainous, more or fewer unbridged river crossings - they will also have different political characteristics: more of less taxed, more or less effectively policed.</p>
|
||
<p>Raids by outlaws are expected to be part of the game economy. News of raids are the sort of things which may propagate through the <a href="null">gossip</a> system. So are changes in taxation regime. Obviously, knowledge items can affect merchants’ trading strategy; in existing prototype code, individual merchants already each keep their own cache of known historical prices, and exchange historical price data with one another; and use this price data to select trades to make.</p>
|

<p>So: to what extent is it worth modelling the spread of knowledge of trade cost and risk?</p>
|
||
<p>Obviously the more we model, the more compute power modelling consumes. If the core objective is a Role Playing Games as currently understood, then there is no need to model very complex trade risk assessment behaviour.</p></div></div></div></body></html> |
