Amazing race sim, if you like race simulations of course!
Graphics- Car models and the track layouts are crazily vivid and full of detail. The cockpits are also just like the "real thing." Although, the spectators and off track personnel could be worked on, especially the pit crews. Thats not a big part of racing anyways so it doesn't really matter.
Sound- When you're accelerating at full speed and down shifting, you definetly feel the power of the car kick in. When turned up to the maximum, it feels like ur actually there.
If you buy GTR2, don't forget to get a wheel like the Logitech MOMO which is reasonably priced and works great. I would get the Logitech G25 if it didn't cost so much! The only thing the MOMO lacks is a clutch but the sequential shifter is realistic as most FIA GT sports cars use sequential shifting.
