I still play this game too and it's a classic and original fun. Most of the missions and miscs are simply enjoyable and I've played this game over and over again because it's really addictive.
I also had GTA 1 and London 69 but I've lost them a long time ago. I do remember London 69 which is arguably better than GTA 1 because it was based in London, unique vehicles and unusual missions and music as well.
GTA 1 is okay but the camera kept shaking when driving in top speed as well the missions can be difficult but the music soundtrack isn't bad after all and the people are shouting and swearing when you stood close to them which is funny.
But ultimately I chose GTA 2 for its overall performance than GTA 1 and London 69 arguably.
