StrengthGamer: So let's face it- Gran Turismo 5 has a ton of content. Career Mode places you in a set of races, each with their own class requirements. You start out with 20,000 credits and are thrown into the game with no real direction. If you aren't a huge car enthusiast, or are unfamiliar with the Gran Turismo series, you may become lost. That's what this guide is for.
