That snappy name is the unofficial title of my latest programming adventure called Passenger. It was originally intended to be a remake of Turbo Esprit (a Spectrum game from about 1984), but after developing it, I discovered that due to the type of game Turbo Esprit is, if you write an updated version, you pretty much end up with GTA.
I'm trying to avoid copying GTA, but it's hard trying to think of any new gameplay aspects that they haven't included. Still, it's pretty rewarding to write a free multi-player GTA, even if it's not quite as good (yet).
Anyway, feel free to give it a whirl and let me know what you think.
