I think, that GTA IV was a very good game, the story was darker, than other GTA games, but I liked it, I think, that physics are more realistic, than GTA V, and the atmosphere and many other things about it are very special for me. I remember, that first day, that game was in stores, I wanted to have it as soon as possible, and it happened, I did get it that day somehow. Most times I wanted to finish the storyline, I finished it twice, than many times fought the police with trying to get most wanted levels, and survive as long as possible, meeting random characters, other things I do not remember so much, but I watched cutscenes on youtube numerous times, because I wanted to learn as much phrases in english as possible, and in this game, I simply found it good for learning.
GTA San Andreas, and GTA IV are legends for me.
