One of the best PC games ever made, graphics is still stunning and overall, it's way superior than mediocre games like Cyberpunk 2077. Simply, an incredible open world modded experience that has me glamouring at it's high quality graphics, Easter eggs, missions and humour. One of the best games of all time.

The story shows in an entertaining and satirical way how f*cked up the U.S. intelligence services are. Switching between the main characters offers a nice change of pace. There are also a lot of side quests, some with their own story and some generic, but all fun.
GTA Online offers just as much content as the single player. Coop missions, races, PvP, side activities and now also heists, which are awesome if you can find a good team.

It's a pity you can't choose your own car for the story, as the default cars are very unspectacular. You can of course use another one, but you risk losing it during the missions, along with all upgrades - even if it was stored in the garage.
The other thing that distracted me a few times is the weapon selection: Hot keys don't make sense, because instead of equipping the selected weapon, they cycle to the next weapon and equip that. Your weapon choices also aren't saved properly.

GTA Online sometimes has connection issues and doesn't have any kind of cheat protection. Heists were a great addition, but unfortunately only the host can progress his heist quest. Rockstar Social Club is pretty bad all around (UI flaws, not enough server resources, lack of functionality).
Sadly, the game also has DRM which forces you to go online every so often.

Overall GTA 5 is an outstanding game that sets the bar higher for the quality of all future games in most categories.
