Do choices in gta v impact character relationships?

Quick Answer
No, the choices you make in Grand Theft Auto V do not affect the relationships between the three main protagonists.
Explanation
Grand Theft Auto V is a single‑player action‑adventure game that follows the stories of Michael De Santa, Franklin Clinton, and Trevor Philips as they plan and execute heists. The game offers players a wide range of free roam options and multiple ways to complete missions, but the core narrative and character dynamics remain fixed regardless of player decisions. Unlike some other games that feature branching storylines or relationship mechanics, GTA V's plot progression is linear and the interactions between the protagonists do not change based on player choice. The game emphasizes player freedom in terms of exploration and combat, but the relationships among the three protagonists stay the same throughout the campaign. Consequently, there is no evidence that player choices influence character relationships in GTA V.
