Before I updated the list this morning I explained my reasoning for a few of the placements. Bolivar and Santander were placed with Brazil because I thought it important to have them represented in the game, and since there's no Columbia, I felt they were a better fit to Brazil than anywhere else.Bolívar can't be a Brazilian Great General, he was from Gran Colômbia. Some more regional names should be useful, like Bento Gonçalves or Moreira César. As Brazil also had a military dictatorship, president names like Costa e Silva and Emílio Médici may also be Great Generals.
Similar to why Sitting Bull and Geronimo were assigned to Shoshone, though they really don't 'correctly' fit the Shoshone.
