It's a true masterpiece of a game.

GTA 4 is the ultimate GTA experience - grit, brutal, real, dark, happy, sad, funny ... the whole range of emotions is presented in the story of this fantastic game.
The attention to realistic detail is by far the biggest in any GTA game and I doubt it will ever be surpassed or on the same level.
All the characters, from Niko Bellic to his cousin Roman to Liberty City are beautifully done and top-notch.
The driving is the most realistic and best so far.

I'm sure you can spend hundreds of hours on this gem of a game and never be bored, there are so many things to explore and so many details that give you a very realistic experience like no other.

The PC port is not the greatest, but it runs solid and has benefits, like the enhanced visuals, which are gorgeous, and independent FM radio where you can put your songs to play while driving.
Too bad that they removed some songs and the epic menu theme song from TBOGT.

I cannot believe this game is 16 years old, it's like some lost ancient advanced artifacts - it's that good and super realistic.

Play this game and enjoy the unbelievable experience.
