Personally I want my 1 square back (from builder hut size) I have lost for the last 2 years as an elf compared to a human.
... and the rest!
Elves BH = 9 squares
Humans BH = 8 squares
Elves MH starts as 36 squares
Humans MH starts as 42 squares
Elves Trader starts as 12 squares
Humans Trader starts as 16 squares
Elves MA starts as 25 squares
Humans MA starts as 20 squares
===
Elves total squares = 82
Humans total squares = 86
BUT
As you progress to later chapters the two buildings where Elves have an advantage (MH and Trader) become the same size for both races. So the Humans now have an advantage of 6 squares saved over Elves!
