The only downside is I have noticed are still very few routes. And yes it's true, there are many indications DLC, but that does not bother me. Otherwise, I do not know what you could do even better because with the best will in principle. Yes, yes I know skills and changes in the weather and fuel consumption and endurance race - there are already in detail still room for improvement.
But as I said at the base (racing feeling) can I no longer do things better - therefore from me a clear recommendation to buy !!! As mentioned in other reviews, you can also use the app ForzaHub to come to CR faster.
