I ask this because every racing game fan has their vision of a perfect racing game but for most this game doesn't exist, so what comes closest?

For me it's Forza Motorsports 4. Now most of you will jump at your screen of choice and point out how the game lacks weather and night racing but like I said it's the best racing game to you and I personally hate night racing and as for weather, well I can take it or leave it. So for me, Forza Motorsports 4 is the closest I have to a perfect racing game and therefore the best racing game to ME.

What is yours?

Edit: I asked for your best, I'm not interested in your worst. Let's keep this positive.
