This game would have received a 4-star rating for the challenge and amount of time required to reach 100%. Unfortunately, on May 31 2014, almost four years after its release, the servers were closed down for Gran Turismo 5. There are 2 online trophies, Proud Owner and Course Designer which, though were easy to unlock, can no longer be collected. Therefore, the Platinum for this game is Not Obtainable.

The 2 online trophies can no longer be unlocked, marking the Platinum for this game Not Obtainable. However, if you still wish to collect the remaining 56 offline trophies, then read on.

We recommend going for the Penniless trophy first, which requires you to spend every credit you have. At the start of the game, if you buy a Eunos Roadster J-Limited '91 from the Dealership and add a Sports ECU from the Tuning Shop, you will spend all your credits and unlock the trophy. In addition, there are a few other trophies you can easily unlock from the start, such as Picture Exclusive, Portraitist, and Driving Music, if you wish.

Next, you can start some actual racing. Begin your career by going through the A-Spec and B-Spec, including the Special Events and Licenses as they unlock through your career. Save your money when you can, until you unlock the Multi-Millionaire trophy by reaching 10 million credits.

Once you have the Multi-Millionaire trophy, you can start buying better cars and work towards the Gold Standard trophy, which requires a gold in every race event, license test, and special event. This is the most challenging and time-consuming trophy in the game, though you will probably unlock several other trophies along the way.

After that, it's simply a matter of mopping-up anything you're still missing. Check out the Gran Turismo 5 trophy guide links under our Links tab for specific details to what you need.

Finally, here's a basic Trophy List:

Far less time consuming than Gran Turismo 5 ever was (before the server went down), which required over 300 hours of gameplay, at least. This game will take you only 50 hours, though it depends on your driving skills. Also, there's no online trophies to worry about. Just driving, driving, and driving.

Basically, you'll want to begin by working through and completing all the racing series. This includes Novice, National B, National A, International B, and International A. Do you best to come in first in order to get the most stars and avoid much mopping-up afterwards.

After that, you can complete the Goodwood Hillclimb events and Lunar missions. For these, you only need to win with a bronze.

Afterwards, it's simply a matter of mopping-up whatever you're missing. Check out the trophy guides in our Links page for details on what you still need to unlock. A few tips: when going for the Fanatical Collector, keep in mind that go-karts are the cheapest to buy, and still count as cars. Also, for the Autobarmy trophy, select the Like the wind: Special Route X track, which are two long straight tracks you can use nicely for grinding, while watching a movie on your smartphone.
