Great GTA and has improved big time since GTA 3...
Storyline 8/10: The storyline is great. You start out as a mobster from the Leone family (introduced in GTA 3). You have several missions to protect the mob members and the leader, Mr. Leone. You go on all three of the islands that you are introduced to in GTA 3. The end of the game is surprising and great.
Graphics 9/10: The graphics have improved 100% since GTA 3. All the cars have a smooth surface, unlike on GTA 3. There is no consistant gltichy buildings/roads. Rockstar greatly improved the graphics from GTA 3 to GTA: Libery City Stories.
Sound 6/10: The sounds didn't improve much since GTA 3 and the music was all the same as well.
Gameplay 10/10: The gameplay improved greatly since GTA 3. The guns are more realistic and the missions are way more fun and challenging. Some missions may get you stuck but most of them are pretty smoothly run and explain everything about GTA 3.
