Rewrite Races, so it reads:

There exist Races to which populations belong. All inhabitants of each Country are of the same race.

Those are the races currently available:
* Average guys: These are your average human beings. Average guys are average in all respects, and excel in nothing. Average guys consume Grain as food.
* Robots: Robots have mastered the art of construction and machination and require no Grain. However, they do consume Petroleum and will function less efficiently if their Country has got none. Robots are above average soldiers. Robots consume Petroleum as food.
The Race of each Country shall be tracked in the {GNDT}.

From Government, delete:

Occasionally, a Country may change its Government to another Government of its choice.

Add an Event rule:

Countries may foment Events at any time. Each Event takes a certain integer amount of Periods to take place, as well as a certain cost per period. An Event may also require a certain cost so it can be started. Any population cost must be deducted from the Homeland of the Country who is fomenting the Event. An Event may list a number of Requisites that must be met by the fomenting Country, before the posting of the Event.

A Country may announce the fomenting of an Event on the World page by adding “Fomenting: (name of Event), (amount of periods left) periods left” to the World wiki page, under the Events title in eir Homeland listing, and paying the initial cost, if any.

A Country may not foment more than one Event at a given time

Often, a Country may pay the cost listed to advance a fomenting Event one Period. Whenever a Country advances a Period in an Event, e must subtract 1 from the amount of Periods listed on the World page for that Event. When that amount of Periods has reached zero, the Event happens, its effects take place and its listing in the World page shall be deleted.

The following Events are currently available:
