Everything that we are seeing in need for speed world can be read, doesn't mind if its serversided or not, even if its in binary code... if your computer reads it why not make a replica code... the texture and the modeling parts like the whole world and all the cars... i think that's the easy thing... the hard thing its programing the moves and of course the money, the server, and taking the risk for this illegal thing...
correct me if i'm wrong
...sorry for my bad english...
