In-game money is bet on different commodities in hope that that particular commodity will become the most valuable as the game progresses. Often the values of the commodities are continually changing throughout the game, and the players buy and sell the commodities to make money off of their investment.
Hand management games are games with cards in them that reward players for playing the cards in certain sequences or groups. The optimal sequence/grouping may vary, depending on board position, cards held and cards played by opponents. Managing your hand means gaining the most value out of available cards under given circumstances. Cards often have multiple uses in the game, further obfuscating an "optimal" sequence.
compared to Port Royal, a quite boring, luck based game that is only interesting in the last 5-10 Minutes.
It's OK but nothing particularly special. It's basically a game where you hope that everyone else doesn't pick the same option as you do, and that gets stale pretty quickly.
My favourite mechanism is simultaneous selection. This is it in its purest form. The game is easy to explain and is instantly exciting. Every turn is a hard choice between what is best or what is safe. It's not great at all player counts and there's not much to it, but it does what it sets out to do very well.
