Information on the way Thorvald will be running the UN (now also added to the OP)
The UN will work a little differently than you're used to. Thorvald will serve as in-game Secretary-General to organize and moderate debates. Resolution proposals will occur in two stages: in the 'debate stage', any member state can propose a topic, or even a full draft, and the other members will discuss it as usual during the turn to work out compromises and/or reword the text to create the 'best' version of a resolution. In the 'voting stage', the Secretary-General introduces the final draft for an official vote, and this will take only 12 days. Every turn a list of motions under debate will be posted, as well as intended voting days for completed resolutions so that no-one is caught unawares.
Besides voting on resolutions, players have the opportunity to work with several pre-established agencies on issues ranging from economic development to climatology and world health. These organisations also publish periodical reports on global trends and outstanding countries to further inform players how their nations measure up, and forewarn areas of impending crisis. You can, of course, choose to shun the UN completely, but at the risk of squandering valuable international expertise. You'll have to determine for yourself if the trade-off is worth it.
The exact design of the UN at the start of the game will draw inspiration from signups, so consider your country's international outlook in your backstory.
