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 comptent 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.

Les bonus obtenus sont visibles à différents endroits : → dans le Royaume où sont rappelés tous les Bonus de nation → dans le rapport du T0 où tous les bonus sont obtenus sont présents (Nation et Personnage)
