Niko's design underwent a few changes, but was finalised early in development. His outfit underwent several changes based on Eastern Europeans, particularly photographs of men fighting in winter wars in Yugoslavia and Chechnya. The primary motivation for the design was a face to convey the appropriate emotions and a body that could move nicely with the new animations. The in-game purchasable outfits were also designed to fit with the character. The team ensured that the gameplay choices presented to the player were not too extensive, as they still had to make sense to the character, who is driven by the people around him. Dan Houser felt that the missions in "San Andreas" had become too linear, and wanted to present choices to the player in "Grand Theft Auto IV".
