There comes a game like that testdrive unlimited, don't know if it's on the internet, but it's on Xbox360... you cant get out'of your car, but you have radio, wipers and stuff,
But if LFS would be the sims, LFS and GTA in one it would be cool,
and stealing cars would only be possible with a kit you know, you could jack a ride and sell it, and for more expensive cars you could have a better kit and less chance of stealing, you could buy new cars with all the painting good, or you could buy 2nd hand with rust and stuff.
It would be very nice i've thought 4 years ago of some kind of game, but it will never come i think. Cause it would be like €1000,- for the game, and developing would be like 5 billion dollars :P, and how would you do the controls, you drive with stearing wheel, you walk with keyboard and mouse, you jack with keys A till Z like in splinter cell.
and with jobs like police and stuff, you can get cought by police, you don't have guns
you know things like that, I would love it
