Day 1: just experience the game, buy a cheap car, race on a few tracks, upgrade the car, maybe even win a race or two. And probably spend an hour ogling all the cars in the showroom. Week 1: have at least one decent car; nothing mega-expensive, just an Audi R8 or Nissan GT-R. Post some stuff in the photo mode forum. Month 1: Have unlocked a good portion of the career mode and be experiencing everything the game's got to offer. Year 1: hopefully platinum it if there aren't any ridiculous trophies like that Vettel X2010 thing in GT5.
