El Grande is a strategic board game set in medieval Spain, where players take on the roles of powerful nobles vying for control over various regions. The game involves placing caballeros (knights) in different provinces, using action cards to influence the game, and managing resources to gain points. Players must balance their influence while anticipating opponents' moves, as the game encourages both direct competition and strategic alliances. The game is played over nine rounds, with the winner being the player who accumulates the most victory points by the end.
