GTA V? Really? I absolutely hated the story in that, and I hated the characters. Here are some of my issues with it:
Trevor:
interesting epilogue, but otherwise pretty much no character arc
really wanted to see him try to take on the Los Santos gangs (DLC!)
Franklin:
largely just does whatever Michael says
wanted to start a dealership, but he kinda gives up once he makes it big (DLC!)
Michael:
arc was okay, but he didn’t seem like a good fit for main character, especially when Franklin gets the ending
All in all, I felt like the three character perspective was largely a distraction from the lack of actual storytelling. SA and IV didn’t have that, so they actually had a meandering plot with some character development to round it all out.
I haven’t finished RDR2 (it’s so long!), but I really loved RDR and heard that story for RDR2 is even better.
