Now Beltrando is the head of publisher Sorry We Are French, and these games are coming back in new forms, with Koryŏ and Chosŏn being reborn as NINE. An overview:
In NINE, you play influence and hero cards in each round of the game, then use their abilities to gain the most victory points during the endgame scoring following the end of the eighth round.
That description is brief, but you can likely extrapolate from my 2013 overview of Koryŏ to get a sense of how to play NINE:
Players then reveal cards in clockwise order from the round's starting player, and for each majority they have among all the character cards in front of them, they might receive a special power. If you have the most bankers (#6), for example, then you take a 1 VP token from the center of the table; having the most spies (#2) lets you steal a 1 VP token from someone else. After you've all revealed cards and used whatever powers are available to you, you discard cards from the table (if needed) to meet that round's card limit.
At the end of eight rounds, you tally points, scoring as many points for a character type as the number of that character — but only if you have more of that character than each other player.
[Koryŏ is] a quick-playing game that combines majority-scoring and special powers in about as tight a manner as possible. You want to expand in every direction to get bonus powers and score majorities — nine points is huge! — and you want to protect what you already have to keep getting powers, but you're limited in what you can play each round with a fresh hand of cards form which to consider.
Players can duck out of rounds at any time, and they'll frequently want to do so as they draw cards only by spending activation tokens (and you have only two each round) or by using goblin powers (which also requires tokens). In addition, if you want to play level 1 cards for a clan not already in your army, you must first discard two cards to do so, making it expensive to recruit new forces — but you can't play level 2 and 3 goblins without a level 1 goblin of the same clan in play. As in life, goblin management is the key to long-term success.
