I originally bought this game for the playstation one when it came out about 10 years ago, it is identical to the original GTA albeit set in London during 1969 (as the name implies). The premise is identical: you are sent to a bank of phones to begin new missions, the missions are all very formulaic, mainly utilizing vehicles that you steal along the way. Sometimes you'll be required to fit a car with a bomb and blow up a police station, take out a gang or some other criminal act.
You can get various weapons and upgrades, beginning with the simple punch attack you can upgrade to a pistol and a machine gun, and also collect body armor, health and police bribes to lose your wanted level. The wanted level is raised when you commit crimes like killing people and blowing up cars and if you don't lose it the police will gradually hunt you down. The cars are all based around the cars of 1969 London, with minis black cabs, London buses, motorbikes and many more.
The game is still fun to play, although I always disliked not being able to see what was up the road; you'll frequently hit oncoming cars if you are driving a particularly fast car like a police
car or a jaguar. Sometimes you can also get lost, the roads can be like mazes sometimes and a knowledge of your surroundings helps when you need to collect a specific upgrade.
All in all it is a very simplified version of the seminal GTA 3, and for younger people that didn't grow up with such games it is interesting to see how the game evolved into the franchise that it has now become. I personally prefer this version to the original, it has more character (maybe because I'm English), and when you die it even says 'you're brown bread' which is a nice bit of cockney flavor. When it came out this game was exceptional and me and my friend took turns playing it for days on end. If you liked any other GTA you will probably like this, I'd have to give it 8/10.
