If a player wants to create a character who is Popular or Famous in Eastern Europe and western Asia, then it is perfectly legitimate to define Eastern Europe and western Asia as being a Large Nation. Also, character should usually be a allowed to include minor areas as belonging to larger Extents, when that makes sense, for instance on Ärth Sláine of Ulster is Popular in Ireland, but he spends a lot of time on the Island of Skya, so even though Skya is part of Britain, not Ireland, the GM of any such campaign should allow Skya to be included in the definition of the Small Nation of Ireland, for the purpose of Släine's Popularities and Reputations (but not Area Knowledge skills; these are easy to buy seperately). And please note that the Island if Skya is small relative to Ireland. Ireland is a Small Nation (Ex2), and the Island of Skya is a Region (Ex4).&lt;/del&gt;&lt;/div&gt;&lt;/td&gt;&lt;td colspan=&quot;2&quot;&gt;&amp;nbsp;&lt;/td&gt;&lt;/tr&gt;

If a player wants to create a character who is Popular or Famous in Eastern Europe and western Asia, then it is perfectly legitimate to define Eastern Europe and western Asia as being a Large Nation. Also, character should usually be a allowed to include minor areas as belonging to larger Extents, when that makes sense, for instance on Ärth Sláine of Ulster is Popular in Ireland, but he spends a lot of time on the Island of Skya, so even though Skya is part of Britain, not Ireland, the GM of any such campaign should allow Skya to be included in the definition of the Small Nation of Ireland, for the purpose of Släine's Popularities and Reputations (but not Area Knowledge skills; these are easy to buy seperately). And please note that the Island if Skya is small relative to Ireland. Ireland is a Small Nation (Ex2), and the Island of Skya is a Region (Ex4).&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

Banks science fiction novel &amp;quot;The Algebraist&amp;quot; (from the perspective of the so-caleld Dwellers&amp;quot;. Given how much real estate there is in Jupiter and its moons (even just the four largest ones), that should count as ExC9, same as the Inner Solar System. It's a bit on the small side for that, but on the other hand it's much too large to count as ExC8.5, at least after decades of colonization and exploitation.&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;
