Quite simply, yes.
New cars to try out, and new tracks to do that on - plus new physics and more photo opportunities to keep it all real.
1. New cars
2. New physics.
3. Silverstone.
4. New track editor.
5. Shelby GT500.
6. New cars and tracks added regularly as DLC.
Nothing is really exciting me greatly so far. There are obviously nice new additions and upgrades but nothing has wowed me yet.
