Tout comme son inspirateur, SdaGame permet également à chaque nation de se différencier par des pouvoirs spécifiques, impactant ses armées, ses héros et/ou son économie. A la différence de son prédécesseur, il s'agit d'une option de jeu et non d'un impératif. Dans les descriptifs de chaque nations du scénario Troisième age - 1650 sont ainsi explicités ces bonus dans le cas d'une partie avec “Bonus de nation : Rigoureux (6 bonus fixes)”, qui peut être considéré comme le mode par défaut. Attention, les bonus terminant par dans leur description compte pour deux!

En plus de ces bonus de nations, les héros peuvent aussi recevoir individuellement des bonus à leurs compétences de base et les CdP, des bâtiments tirés aléatoirement en début de partie.
