Did you ever play Driver for the PS 1? I think it was the first game to give gamers the ability to roam freely from one city to another in full 3D! I consider it the first 3d GTA game (though it was not under the GTA franchise). The first Driver had a bit difficult training stage at the beginning of the campaign. You had to master slaloms and such before you could accept missions across the city. It was such a wonderful experience to drive through cities and try to achieve different objectives. I wonder if they'll ever revive this series.
