I don't know about GT4 but I say NFS:MW isn't the best.
What I want EA to do is to have all the graphics from all of NFS (Underground 1, 2, MW, Carbon) with all the customizations especially from underground 2 and carbon and lets not forget about the police. Then with a hint of GTA 4. Able to get out of your car and stealing others, run people over and able to shoot guns.
Oh and a really big map!
Now that will be a really good racing game.
You mean like....GTA4?
Best racing game to me is Forza 2.
