I mean, I’d argue that GTA V didn’t have the most emotional storytelling, but it wasn’t a character driven game like RDR2. The characters had the stories they did because they each opened up different avenues into different types of crimes. They didn’t focus on it. The characters were all insufferable. But that doesn’t mean the writing for the story itself wasn’t good. Yeah, the characters all kinda sucked, but the storytelling propelled the tension and wasn’t just some lame bullshit that felt like it needed to be there. The characters don’t develop that much, but the backstory was great, the intrigue and the vastness of the word made it great. That’s all writing. But you’re right, it couldn’t stand alone as a character driven story.
RDR2 on the other hand is a character driven story at its heart. You definitely need to play it because it’s incredibly well done. If you’re looking for good storytelling, emotional connections to the characters’ trajectories, and a great fuckin game, RDR2 is where you wanna be.
