I think enough time has passed where we can talk about this game objectively. It's easily apparent that while GTA V is loved by many, it doesn't stand nearly as tall as it did on 9/17. So I might as well dive into the problems I had with the game.
1. The game is not really revolutionary. Just feels like a refinement of previous GTA games.
2. The freeroam hasn't changed one bit. You just hijack cars, escape cops, harass people, and cause destruction. All the same things I did in San Andreas. Except in HD.
3. High lethality shortens your exploration freedom. It's near impossible to bike on rough terrain for too long.
4. The radio station songs (aside from the subjective complaint of being bad) are too scattered and random to capture a particular mood of any sort.
5. The heists have really limited choices (some having none at all). Basically, A or B. And, the guy who sucks or the girl whose good. None of them were as good as GTA IV's Three Leaf Clover.
6. The satire in the game is dull. It tries to take on as many groups of people as possible but has no real message other than pissing people off because it's funny. Unlike GTA IV or San Andreas.
7. Character inconsistency in the story. Characters were hotheaded when it fueled the plot but coolheaded when it would've caused a story problem. For example: Madrazo was a cut-throat mob leader, but tolerated Trevor kidnapping his wife and slicing off his ear without any pursuit of revenge.
8. The plot really doesn't lead anywhere. The climaxes are mainly just characters screaming at each other and insulting each other.
9. Los Santos is a big city but feels diluted. There's proportionately less interiors in the series than there ever was.
