So I have almost completed them due to some helpful advice and absolute luck.
One or the other......
BTW I have now managed to comple 39 of the 51 event maches, the one that I'm really having trouble on is the Marathon Man one. the time goes faster than normal to add to the faster cars.
No, if you have four contollers, or less, put them all in, and start a game using all of the controllers, let it run for 5 hours (4 contollers) 6 hours forty minutes (3 controllers) 10 hours (2 contollers) 20 hours (1 controller) you probably won't need that many, but, this is on the assumption you're NEVER played Versus mode ever.
