Features are bound to be dropped at some point in the GTA franchise, but it's often a shock when that feature is only present in one game.
Sometimes, a feature is dropped because a better one replaces it. However, the features streamlined in this article are ones that fans adored. Even in instances where it makes sense, fans are still disappointed to see these features removed.
As "features" is a bit of a broad term, it should be noted that this article will refer to anything the player can do in GTA as "features." Graphical improvements and radio stations won't be a part of this list, as these features have to be something the players can actively do themselves. Predictably, it won't include features that could return to GTA 6 as this article was written before GTA 6 was officially announced.
