If you want to sit in a virtual cockpit which lets you feel the Alcantara, you'd better wait for GT5. If you'd rather race Maranello's finest in an arcade setting, there's always OutRun Online Arcade (although tragically, for those that don't have it, it's no longer available on PSN). And if you're just after a great racing game, the list of suitors is as long as the Scuderia's history. There is a Ferrari experience here, as long as your idea of the Ferrari experience is a Toyota MR2 with an ill-fitting F355 replica bodykit.
Ferrari don't make video games... but perhaps they should.
