I sort of figured that's what u meant. Seeing what you have done, I just gave it a shot to lure you into making GTA SA Java.   It would be really great to see some completed Java games really making use of 3D though. lwjgl 16K GTA SA? U know u want to  

do something like GTA1, giving the user a real feeling of speed, zoom the camera out with increasing speed...forget about the weapons and do something like DRIVER instead, where the whole point is to drive from A to B but encountering numerous obstacles like Police, Road Blocks etc.

Make it really hard to complete but add nice and easy controls and I'll surely buy it.
