The CEO of Take 2, GTA's publisher talking about how he will force microtransactions into every single one of their games, they want more the $60+ that we all pay for the game but hundreds over the course of your play time regardless of the game.
Educate yourself, read how bad these people are know your enemy as a gamer, as a consumer, is: https://www.gamasutra.com/view/news/309190/TakeTwo_plans_to_only_release_games_with_recurrent_consumer_spending_hooks.php
Single player, still good, as with most if not all GTA titles thus far, playing 3 different characters is both at times tiring and fun. One of the 3 is the least interesting, that being Franklin, his character was the least fleshed out yet was made out to be the glue to the group. The gameplay is mostly better and for it's time it looked great though now visually not as impressive, there are however still instances where the world lives and you just sit back and watch.

By now you already know what the story is about, you do heists, which compared to PD2, are quite well done and make you feel like you're actually getting something out of it after you've planned for several set-up missions. Your characters level up their traits so the now bog standard RPG elements are built into the game, for better or for worse which means at times a lot of grinding in order to get better which again is forced and boring in any game. All in all the story is worth it so long as you find the game on sale, NEVER pay full price for this title as it is simply not worth $60 for a 4 year old game, period.

Now the online aspect of GTA5, where to start.... well it WAS a fair sandbox where you could enjoy getting killed by random a-holes in the server but now you can get that same feeling while you're flying, riding in a tank, anywhere you go you will be harried by other players in Freeroam. It was a horrible design choice and I will never understand what they ultimately thought would happen. That's just the crappy overworld, joining matches is a chore if you can even find anything then have fun with the infinite number of game modes that Rockstar keeps shoving out of the door to keep people playing because you'll never find a game mode beyond it's initial introduction. By the way that’s if you aren’t killed by the countless modders that have been a problem since day 1 of the PC release but does Rockstar do anything? No they go after the victims rather then the offenders.

On the subject of stability or how good of a port GTA5 is over all, it is pretty good but it also isn't, the load times are insane, even having the game on an SSD it can take at times an unlimited amount of time to load/connect to an offline lobby. While the game runs fairly well Rockstar clearly did not make sure that stability and reliability was mirrored during loading and connecting to a lobby. Sorry but a 4 year old game if it's well optimized should not take 5+ minutes to load on an SSD or any hard drive for that matter, period.

How they treat their paying customers and loyal player base is also shameful, their support staff, if you can call them that, do nothing but read from prefabricated responses and treats you like you caused the issue to happen. They constantly suggest over the top things to fix completely separate issues, like uninstall our 50+ gigabyte game and reinstall it in order to fix a connection problem. Not to mention the countless false positives for account bans and account wipes, which means that even a straight as an arrow player can and will get banned or have all of their cash wiped entirely from their character just because their “state of the art trusted anti-cheat” system flagged your account. They constantly blame the victim rather then the cause and their support staff are instructed not to speak to anyone regarding bans or said money wipes. They have constantly denied any and all wrong doing on every account even when given mountains of evidence they are staunch in their “belief” that you are the problem and not their system.

Making money, which is the only way to really get anywhere in the game, because it's not like I want to play the game that I bought, no I want to literally work for hours at a time grinding missions, heists, game modes, etc. Just to get anywhere in the game. If you don't grind for cash or pay for in game money you will suffer, the poor are indeed the lesser class in GTA Online with no real way to gain serious money if they can't find the means or the tools. You can't get the tools if you don’t have the money and if you don’t have the tools you can't make the money. It's a horrible circle and it does not make a fun game to just enjoy, because you can't because it's work, you're quite literally working within the game universe. If you own a business, you're doing work, if you're trying to make money via heists (which is no longer the best way to make money these days, anymore anyway) you work and grind for DAYS on end. With the amount of time that I spent working in GTA Online, comparing their own pricing for Shark Cards I would have spent thousands of dollars to give you some perspective and I still don't own everything, not even close. Everything in Online is now priced so that it all but forces you to buy Shark Cards which Rockstar's fee to pay microtransactions. The best part about them now is that they are totally worthless, with each update that Rockstar releases the items get more and more expensive to the point where even the $100 Shark Card for $8 million, won't even buy you a car or two, where as before when the game was first out you'd be hard pressed to spend all $8 million. It is done on purpose and now that Take 2's CEO has consistently come out to the public and investor meetings and stated that he treats customers by how they spend on his games. That should tell you what kind of horrible person and horrible company Take 2 and Rockstar have turned into.

Their CEO is on record comparing paying human customers to minnows, dolphins and whales, these dehumanizing categories put gamers into their spending habits, if you spend very little and simply grind for days on end for your cash well you’re a minnow, if you buy money constantly then you’re a whale. These are the people running Take 2 and Rockstar, these are the people saying making games is too expensive, the “people” who compare human beings to aquatic creatures based on their spending habits.

Do yourself and your fellow gamers some respect and avoid this title, educate yourself on how badly Take 2 and Rockstar have been treating their own paying customers for the past 4 years and realize that it will NEVER go back to the way it was. Take 2 and Rockstar will never be the same again, and when this microtransaction bubble bursts, because it will, Take 2 and Rockstar will be gone because they've now made sure that if their ideas fail their companies fail. It's better to please your investors then your actual customers, the ones who make your fame possible. Spend your money on another more deserving company, please.
