GTA IV went against the direction of the series. Instead of carefree fun, it offered a heavier tone, a more restrained city and physics that have not been repeated since.
Technically, GTA IV differs from the rest of the series mainly through one feature, and it is not the graphics. It is how characters move.
Instead of playing prepared falling animations, Euphoria calculates the body's response in real time. A character reaches for a railing, bends their knees and tries to keep balance. No two falls look alike.
GTA V and Red Dead Redemption 2 use the same foundation, but the fifth game restrains the system. Some players therefore still argue that GTA IV moves better than games ten years newer, for a specific reason rather than mere nostalgia.
Try it: The effect is clearest when you hit someone with a car at low speed or fall down stairs. Try the same thing in GTA V and the difference is immediate.
Who Niko is, why he differs from the series' other protagonists, and three choices for which the game deliberately offers no right answer.
Deal or Revenge. Someone dies either way and the money is identical, so the choice is not about the reward.
The Lost and Damned and The Ballad of Gay Tony: the same city with two entirely different moods.
Why a 2008 game can overwhelm a modern PC and which settings genuinely improve it.
