Probably the realest, most serious GTA game out of all of them. Not necessarily speaking about the physics, which are also on point (regarding vehicles, cars in real life are two-ton hunks of steel with a lot of inertia, and makes sense that they are tricky to drive in this game), but just the general feel of the game. It's gloomy, dark, and the colors seem a bit dull at times, further amplifying the bleak factor.
You get ordinary guns, like a Glock or an AK, not things such as minigun or a homing missile launcher, not just because you would not find such weapons in a place like Liberty City, but because they would make the game feel like not much of a challenge.
And regarding the story, I will not give any spoilers, I will just say this: it's immersive and it feels real.
I dare say GTA 4 is better than GTA 5. In almost every aspect.
Wonderful game. 10/10.

Yet another great game ruined by another launcher being needed to launch it. It's like a rocket launch every time you want to open it.
