I played for about 6 hours to date and have to say this is GTA 5 really become a super game. The PC version has been implemented correctly, the mouse and keyboard work perfectly.
Had no crashes and no big annoying bugs. The story and the character are just awesome, the graphics has no reason to complain.
The game world is very large and lively, even underwater, the developers have added a lot of effort.
There are extremely a lot to discover and again you have to laugh, because many sayings are quite coarse.
This game is our society, our world, even if it is oversubscribed.
Apart from the initial difficulties, it is for me, one of the best games in recent years. So much variety can be found in any other game.
You can play golf, tennis, racing, darts, flying, diving, etc etc etc. There are so many possibilities.
Online mode I have not tried, first single player's turn.
All in all, I can only express a purchase recommendation, let us not be put off by the initial problems, who has never played it, the missed something.
