This video is not about realism, its purpose is to point out gameplay value along with minor details. Physics, gunfight, AI, melee combat, controls, interiors, multiplayer freedom. While GTA V has some obvious advantages from being a 2013 game, a lot of technical features and sanbox elements from GTA IV (2008) were missing such as crouch ability, holding onto ledges, picking up objects and much more.
Those notable changes killed all the unpredictable fun and made it an experience with less replay value.
No mods were used, this is the original version of both games on PC. Cheats were used at some point for demonstration purpose, but every comparisons are true and fair to each other.
