It's a love hate relationship with V for me, I enjoy it, but I constantly get the feeling that it could have, and should have, been more. There's just too many blatant cut corners, massive plot holes, errors, and stupid decisions to make the game feel like something else. Rockstar could have expanded the game in so many more ways than just expanding the map. They had so many points in the story where it could have been expanded, even with menial missions, and improved the story. They could have integrated things into the story more, and had less features just half assed in. I have no doubt that the upcoming DLC will improve some of this, but I feel like they tried to fit too much into the game, and came up short in many aspects.
I should also note, the GTA feeling for me isn't the perfect story, or the perfect map, or the perfect setting. It's freedom. It's being able to do literally everything. It's not that GTA V limits you from doing that, because you can, it's that it never feels like it's in character for Michael, Trevor, or Franklin. By the end game, they're all pretty happy and calm, and then going on rampages and killing hundreds of cops and having huge police chases, just feels really surreal and out of character for me. I feel like, even Trevor, had mellowed by the end of the story, he got what he wanted, and has no reason to go mental anymore.
Where GTA V is a fun game, and it's gorgeous, the atmosphere and the way the story plays, and the side stuff you can do, like missions and things, it just doesn't all add up to what I personally think a GTA game should be. It doesn't feel limiting, it just feels a bit wrong.
