Polyphony took their time with this one, and all the love and attention to detail really comes through when you're playing. One of the most feature-packed games this generation has offered so far.
Beautiful, crisp visuals, impeccable audio design, wonderful soundtrack ranging from unique rock songs specifically composed for the game to wonderful piano recordings performed by virtuoso pianist Lang Lang.
Since the game was in development for such a long time and people's anticipation was reaching unhealthy levels, the game was put under extra scrutiny. No game is perfect, but what minor flaws GT5 might have, they are amplified tenfold by internet forum dwellers.
In short, if you like cars, or feel like you want to know more about cars, this is the game to pick up. There is enough to do to last you a lifetime, whether you want to race in unique, manufacturere-specific events or just browse the humongous car list and read up important production cars throughout automotive history.
It feels good having Gran Turismo back!
