GT3 is the best! I got to the point where I actually joined www.gt3times.com and started posting times (handle: "Bolthole"). I take more pride than I would ever admit to my girlfriend in the fact that at the time I posted I had a laptime that was #43 in the world (ok well the tiny world of GT3 Times) on the Midfield track!

I am cautioned though not to leave it on pause for any extended period of time though it hasn't caused me any problems yet.
