I am glad that I'm not the only one that substituted this as GTA at a time that I was not allowed to play the game, as the game is honestly a great sandbox game. I don't really remember anything about the story but the city and exploration is what makes this game so incredibly fun and why I played it so much. The area you can explore is honestly pretty huge and you have a lot of free reign to do and go wherever. There is also a lot of detail in the world, so its not lacking substance either in the areas that you can explore, and there are tons of sidequests and even a lot of one-off areas, and just overall a ton to do in the game if you really want to.
