For my part, I prefer GTA V over GTA IV. To be honest, GTA IV had a realism vibe and Niko Bellic's story was heavy and gritty, but GTA V grabbed me more because of the large open world and three different characters that change the gameplay. The graphics and mechanics were also polished and the many activities kept me engaged for a long time. GTA IV had its charm, but GTA V gave me more freedom and fun with exploration and missions with a wide variety.
