'A Song of Ice and Fire' is also great. There are multiple kingdoms vying for power. Westeros is filled with complex political intrigue among the Seven Kingdoms. Each kingdom has different ruling families, climates, and resources, which all play into the power struggles and the building (and often destruction) of these kingdoms.
One popular kingdom building novel is 'The Lord of the Rings'. It involves the building of kingdoms in Middle - earth, with different races like Men, Elves, and Dwarves having their own territories and forms of governance. Another is 'A Song of Ice and Fire'. There are various kingdoms vying for power, and characters constantly strive to build, defend, or take over these kingdoms. 'The Wheel of Time' also has elements of kingdom building as different nations and regions develop their own political and social structures.
Good kingdom building novels often have complex political systems. For example, in 'A Song of Ice and Fire', the politics of the Seven Kingdoms are full of intrigue, backstabbing, and power plays between different houses. Another characteristic is a well - developed world - building. In 'The Wheel of Time', the different kingdoms have their own cultures, religions, and economies. They also usually have interesting characters who are involved in the kingdom building process, like Kvothe in 'The Name of the Wind' who has an impact on the academic and political aspects of his world.
