OK, I golded the CR-Z race using the cheat button after reading that it was "easy", but in the normal run of things I am lucky to get a bronze in these events. Then again, other than races Golds in most of the other things in the game seem to elude me so just chalk it down to a lack of ability. If I can't at least see some hope of gold in these events, the "fun factor" tends to be reduced to a pointless grind factor which is not what I play a game for, so the end result is that I don't even bother with the things.
Other than the CR-Z one are there any others that could be termed vaguely easy? I did hear that the NASCAR one wasn't too bad, but I am not a huge fan of trying to control the things in the game. Then again there are the cheat buttons!
