Normally in Wealth of Nations you may pass your turn in the trade phase and then trade again later in the phase. This mechanism allows you to hold off if you are waiting for another player to get some cash or finish another trade.
In the cut-throat variant you may not pass during the trade phase. If you do not take a trade action you must pass then you may not trade again during the current phase. Taking out or paying off a promissory note does not count as a trade action.
This version of the game leads to a lot more tension in the trade phase since you cannot sit back and see what happens before you commit to your trades. Also players have to be more careful about procuring food and energy for the upcoming produce phase.
Seems like this would result in many more smaller trades where you only trade one cube on your turn just to stay in rather than do larger trades. Does this occur? And does it lengthen out the trade phase significantly (enough to make it tedious)?
