Indeed like GTA3 but more mission driven, but very good and interesting missions. In some of them you think you almost completed the mission but then something happens, and you realise you still have a long way to go. The mission where you have to race was really hard to me, but after a 20 times i finally beat it. And i'm sorry to say that it isn't possible in to save whereever you want even not in the full game. But the game is still worth it.
